I think i'm finally getting the hang of making french bread. I won't say my recipe/technique is perfect, but I finally feel confident enough to share bread with freinds. Here's some pictures of what I've been up to.

I've been enjoying these results, but I can't seem to get an even oven spring. That is, where I slash the dough either pops too much or too little while baking. Any ideas how to get a more consistent pop?

Details on what I actually do: http://wchernoff.wordpress.com/2010/07/24/feel-that-oven-spring/

Questions regarding how to convert one kind of starter into another are frequently asked on The Fresh Loaf. The easy answer is to just take "a little bit" of seed starter and add enough flour and water to make a mixture of the desired thickness. This is fine and it generally works very well. However, sometimes a recipe calls for a precise hydration level levain and changing this, even a few percentage points, will make the dough consistency quite different from that intended by the formula's author. For those times, one needs to be more precise in making up the levain. 

To convert a starter of one hydration to a starter of another hydration - For example, if you have a 50% hydration starter and want to build a 100% hydration starter from it. 

Here's a general method for a precise conversion:

First, you need to know four things:

1. What is the hydration of your seed starter?

2. What is the hydration of your final starter?

3. How much of the total flour in your final starter comes from your seed starter?

4. How much (weight) final starter will you be making?

Second, you need to calculate the total amount of flour and the total amount of water in your final starter.

Third, you need to calculate the amount of flour and the amount of water in the seed starter.

Fourth, you can now calculate the ingredients of your final starter. They will be:

1. Seed starter

2. Flour (from seed starter plus additional)

3. Water (from seed starter plus additional)

So, let's see how this method works with some specific assumptions. 

The four things you need to know:

Assume you have a 50% hydration seed starter that you want to use. Assume you want to make 100 g of a 100% hydration starter. And assume you want the seed starter to provide 25% of the total flour in the final starter.

Note: Using "Baker's Math," Flour is always 100%, and all other ingredients are proportionate to the flour. So, in a 50% hydration mix, the water is 50% (of the flour, by weight). If hydration is 125%, the water is 125% (or 1.25 times) the flour.

To calculate the total amount of flour and water in your final starter:

Flour (100 parts) + Water (100 parts) = 100 g

So, the 100 g of starter is made up of 200 "parts." The weight of each part is calculated by dividing the total weight by the number of parts. So, 100 g /200 parts = 0.50 g.  This number is sometimes called "the conversion factor."

Then, since there are 100 parts of flour, its weight is 100 parts x 0.5 g = 50 g.

The total water in the final dough is 100 parts x 0.5 g = 50 g.

To calculate how much flour will come from the seed starter and how much will be added to make the final starter:

We now know that the total flour in the final starter will be 50 g. But we decided that 25% of this flour is going to come from the seed starter. This means that the seed starter must contain 50 g x 0.25 = 12.5 g of flour, and the flour added to this to make the final starter will be 50 g - 12.5 g = 37.5 g.

To calculate the total weight of the seed starter and the weight of water in the seed starter:

We now need to calculate how much seed starter it takes to provide 12.5 g of flour, and how much water is in this amount of seed starter.

If the seed starter is 50% hydration, it contains 100 parts of flour and 50 parts of water. We know then that the amount of water is 50 parts water/100 parts flour = 0.5  parts of the flour.  Since we already know that the flour has to weigh 12.5 g, then the water must weigh 12.5 x 0.5 = 6.25 g and the total weight of the seed starter is the sum of the water and flour or 12.5 g of flour + 6.25 g of water = 18.75 g.

To calculate the weight of water that must be added to the seed starter to make the final starter:

Now we can calculate how much water must be added to the seed starter to make the final starter. It is the total water in the final starter minus the water in the seed starter or 50 g - 6.25 g = 43.75 g.

Now we know "everything!" To make 100 g of 100% hydration starter, beginning with a 50% hydration seed starter, we would mix:

1. 18.75 g Seed Starter.

2. 37.5 g Flour

3. 43. 75 g water

This method can be used to build any amount of starter of any hydration using a seed starter of any (known) hydration.

I have read so many bread baking books and viewed so many videos on shaping boules, but I didn't really "get it" until I saw our instructor, Miyuki, do it in the SFBI Artisan I workshop I attended a couple weeks ago.

I will attempt to show what I learned in still photos with descriptions. I hope that viewing these and then reviewing some of the excellent videos available might help others who are struggling with this technique.

Mis en place

You will need:

1. a batch of fully-fermented dough

2. a lightly floured "board" on which to work.

3. a scale, if you are dividing the dough.

4. a bench knife or other cutting implement, if you are dividing the dough

5. prepared bannetons or a couche on which to rest the formed boules for proofing

Procedure

1. Weigh your dough

2. Divide it into equal pieces.

3. Pre-shape each piece gently, incorporating any small pieces of dough on the inside. 

4. Rest the pre-shaped pieces, seam side down and covered with plastic or a towel  on the board for 20-30 minutes.

5. Prepare your bannetons or couche for receiving the shaped boules.

6. After the pre-shaped pieces have rested, shape each as follows:

* Pick up the piece and turn it smooth side down.

* Gently fold the long ends together under the piece.

* Rotate the piece 90º in your hands, and fold the other two sides together.

* Place the piece on an un-floured board, smooth side up.

* Cup your hands around the piece, and gently drag it 3 inches or so towards you in such a way that the edge closest to you sticks to the board and is dragged under the dough, thus stretching the top of the piece into a tight sheath containing the dough.

Note the position of the markers before stretching

After the stretching, the marker at the apex of the boule is unmoved, but the one that was at about 40º North, is now about at the equator.

* Rotate the dough 90º and repeat. Do this 3-4 times until the bottom of the boule is relatively smooth and the whole boule has an unbroken, smooth sheath.

Note that there are no visible seams on what will be the bottom of the boule, after the procedure described.

* Place the boules in bannetons, smooth side down, spray with oil and place each banneton in a food-grade plastic bag to proof. (Alternatively, place the boules seam side down on a couch and cover with a fold of the couche, plasti-crap or a towel.)

Well, there it is. For me, being able to visualize the stretching of the "skin" of the boule between a fixed North Pole and a point on the side, using the board to "grab" the bottom of the boule as I dragged it towards me was the "aha moment." I hope it makes sense to others.

The goal (to form a tight gluten sheath) in forming other shapes is fundamentally the same, but the method is entirely different.

Comments and questions are welcome.

Happy baking!

I've spent the last couple weeks working on a french style loaf.  I think my recipe and technique are getting better, so I figured I'd post my efforts for others to review.

Steps available: http://wchernoff.wordpress.com/2010/07/07/feel-that-oven-spring/

Notes:

1.  I've used this recipe with 17 oz of flour and 11 oz of water (a change from 62% to 65% water) which seemed to make a lighter/holier loaf (sorry but not pics).  Has anyone noticed this effect?  Also this change results in a softer dough, so I had to be quick about slashing the tops. 

Questions:

2.  How can one prevent the razor from sticking to the dough when slashed?

3.  My oven doesn't conduct heat correctly when adding water for steam.  How does a spray bottle compare to a cup of water for producing steam?

Hey there everyone.  Well I'm emerging out of hibernation to tell you about my latest project.  Last spring I started working on a couple of instructional baking DVDs but I never finished them before the busy season hit.  Then when I got back to work on them this fall, I decided to re-shoot the whole thing and spend some more time on them. 

Well, I just got finished. 

I had a different focus for each video.  The first DVD is for the baker who reads a recipe and wants to see exactly what the dough is supposed to look like at each stage of the process.  I showcase three recipes and I demonstrate how I work with each of them 'from start to finish'.  Two of the doughs I mix by hand, one with a mixer.  I voice over while I'm working so there's no standing around watching the dough dry.  Anyway, here's a preview:

The second video focuses on the entire baking bread process from scaling to mixing in more detail - although I include the same recipes for you to try out as the first video, I demonstrate techniques using different doughs like rye, sour white, and baguettes (no recipes for those).  This DVD is more for the baker who already has a favorite baking book and/or recipe, but would like to improve their skills a bit.  You can see that preview here:

Well, let me know what you think, and if you have any questions regarding them, you can ask right here!

If you'd like some more info about the DVDs you can visit our website over here.

Like many people, I found TFL in my quest to learn how to make sourdough.  I had a starter going and was sure I had killed it.  The advice I found here gave me the knowledge and confidence to make a starter that I've been using for months now, with ever-better results.

Although there is a wealth of information here, there was no one source that detailed the method I used, which was based on Reinhart's "barm" in BBA.  Now that I have succeeded in making several starters, I've been thinking about making a video tutorial to walk through the process step-by-step, day-by-day.  My own experience and that of others here has taught me one thing:  sourdough starters don't read baking books, so they don't know how they are "supposed" to behave.  I could have been spared the angst, the wasted time, and of course, pounds of precious flour, if only I had known what to expect and what to look for. 

I don't have the technical part of video-making worked out yet, so I have decided to do a tutorial blog.  This will be a real test, as I am trying out a modified starter that I haven't made before.  It's still based on Peter's starter, but I have altered the amounts, and possibly the times, to suit my own fancy.  If all goes well, I will end up with a more reasonable (i.e., much smaller) amount of starter, and I will get there with much less wasted flour.

So here goes:

Day 1: 

Ingredients:  1/3 cup rye flour and 1/4 cup water

For the flour, I use stone-ground rye.  Nothing special, just what I got from the grocery store.  My water is tap water run through a filter.  Before I had he filter on my sink, I used bottled drinking water.

Mix the flour and water in a bowl.  It will be thick and pasty, kind of like the oatmeal that's left in the pot if you don't come down for breakfast on time. 

Once all the flour is mixed in, put it in a pint-sized or larger container and cover with plastic wrap.  Leave it out on the counter. 

And that's it for today.

Day 2:

Ingredients:  1/4 cup unbleached AP, bread, or high gluten flour; 1/8 cup water

There should be little, if any, change in the culture from yesterday.  Again, I'm not really particular about the flour.  I would just recommend staying away from bleached flour.  I am using AP flour for this batch.

Mix the flour, water, and all of the starter from yesterday in a bowl.  It will still be thick but a little wetter than yesterday. 

Put it back in the container (no need to wash it), press it down as level as you can get it, and mark the top of the culture with a piece of tape on the outside of the container. 

Put the plastic wrap back on top, and you're finished.

Day 3:

Ingredients:  1/4 cup unbleached AP, bread, or high gluten flour; 1/8 cup water

Around Day 3 or 4, something happens that puts terror in the heart of the amateur sourdough maker:  they get a whiff of their starter.  When you check your starter on Day 3, you may notice a strange, and not at all pleasant, odor.  And unless you know better (which you will now), you'll swear something is drastically wrong.  In fact, I would venture to guess that that smell has been the ruin of more amateur sourdough growers than anything else.  It's an acrid, sour, almost rotten smell, and it's perfectly normal.  And rest assured, your new baby sourdough starter will soon outgrow it.  So, take heart, and press on.

You may also notice that your starter has begun to come to life.  It probably won't grow a lot, maybe 50%, but you will start to see bubbles, like these:

Regardless of the amount of growth, stir down your starter, throw out about half (no need to measure, just eyeball it), and mix the rest with today's flour and water.  You will get a slightly more doughy-looking mass:

Once it's well mixed, put it back in the container (still no need to wash), pat it down, and move your tape to again mark the top of the starter.

Put the plastic wrap back on the container, and take the rest of the evening off.  You worked hard today.

Day 4:

Ingredients:  1/4 cup unbleached AP, bread, or high gluten flour; 1/8 cup water

And now, a word about measurements.  If you bake regularly, or even if you've just been nosing around baking sites for a while, you are no doubt aware that the ingredients in most artisan bread recipes are listed by weight rather than volume.  I measure by weight for my baking and for maintaining my sourdough starter. 

You might wonder why, then, am I using volume measurements here?  Two reasons: first, I have tried to make this starter as simple to follow as possible -- no special tools, no monkeying around with the scales, just a couple of measuring cups and a bowl.  And, when it comes to starting a starter, the measurements aren't as critical as when you actually go to bake with it.  So for now, we're just using measuring cups. 

Today is another one of those days where novice sourdough starter makers often lose heart.  Your starter is now coming to life, and like most living things, it kind of has a mind of its own.  Up until now, we followed the clock, making our additions every 24 hours.  Now, we will be letting the starter dictate the timeframe. 

Before you do your Day 4 additions, you want to make sure your starter has at least doubled.  If it doubles in less than 24 hours, you should still wait until the 24 hour mark.  If it takes more than 24 hours, be patient.  Let it double.  It may take another 12 or 24 hours, or it may take longer.  Again, be patient.  It will double.  Just give it time.  Eventually, you'll end up with a nice, bubbly starter:

You can see that mine more than doubled.  But I still waited for 24 hours.  Once it doubles, throw out half of the starter, then mix the rest with the flour and water, and back into the bowl it goes:

Replace the tape and plastic wrap.  Then wait for it to double.   It could take as little as 4 hours, or it may take more than 24 hours.  This time, you can move on to Day 5 at any point after doubling.  It's OK if you let it more than double; it's also OK to move on right when it hits the double mark.  So, hurry up and wait.

Day 5:

Ingredients:  3/4 cup unbleached AP, bread, or high gluten flour; 1/2 cup water

Once your starter has at least doubled, it's time for the final mix.

Combine flour, water, and 1/4 cup starter in a bowl and mix well.  Transfer to a clean container with room for the starter to at least double.

OK, one last time, cover with plastic wrap and let it sit on the counter until it gets nice and bubbly.  Don't worry so much about how much it grows, just so that it's bubbly looking.  This will probably take around 6 hours, but, again, don't stress about the time.  Let the starter tell you when it's ready.

When your starter gets bubbly, pat yourself on the back:  you are now the proud parent of a bouncing baby starter!  Put a lid or other cover on your container and put it in the refrigerator.  Let it chill overnight, and you can begin using it the next day.

Day 6 and beyond:

By today, your starter is ready to use.  The flavor will continue to develop over the next several weeks to month, so don't be disappointed if your first few loaves aren't sour enough for you.  I would still recommend beginning to bake with it right away, especially if you have never made sourdough bread before.  That way, you can hone your skills while your starter develops its flavor.

Feeding your sourdough:  If you keep your sourdough in the fridge, you only have to feed it about once a week.  And you can minimize your discards by keeping only what you need and feeding it when you want to bake with it.  I recommend a 1:1:1 (starter:flour:water) feeding, which means each feeding includes an equal amount, by weight, of starter, flour, and water. 

Start by weighing your starter, subtracting the weight of your container.  Then add an equal amount of flour and water directly to the container.  So, for example, if you have 100 grams of starter, you would add 100 grams each of flour and water.  If you feed your starter right out of the fridge, as I do, warm your water to lukewarm (90 - 100 degrees F).  After you mix in the flour and water, leave it out on the counter for a few hours, then put it back in the refrigerator.  It's best if you feed your starter a few days before you intend to bake with it.

To illustrate, here is an example of my feeding routine, starting with the Day 5 starter and assuming that I finished making the starter on Friday night:

• Saturday morning, I take out what I need to bake bread (2/3 cup using my normal sourdough bread recipe) and return the rest of the starter to the refrigetator.
• Wednesday of the next week, I get out the starter, weigh it, and add equal amounts of flour and water in a 1:1:1 ratio, as outlined above.  My goal here is to build up as much starter as I need to make bread on the weekend, and enough left over for my next build.  It's OK if I have more than I need to bake with.  If I don't think I'll have enough after a 1:1:1 build, I will increase my ratio of flour and water, maybe to 1:2:2 or 1:1.5:1.5.  In that case, I will let it sit out until it almost doubles before returning it to the fridge, which might take a bit longer, as I'm using less starter relative to flour and water.
• Friday night or Saturday morning, I again take out what I need to bake with and return the rest to the fridge, to be fed again mid-week.

This is just an example of how I keep my starter.  You can feed yours more often if you bake more than I do.  It's also OK to let it go more than a week between feedings.  If you do that, though, you might want to feed it a few times before you bake with it.

So, that's it.  Hopefully I've unravelled some of the mystery of sourdough starters and given you the confidence to try one yourself.  Good luck, and let me know how it works out for you!

The Fresh Loafers, This is the latest video where I'm working with some higher hydration (68%) doughs. Both of the breads are 'originals', and if you'd like to see the recipes you can probe around here for them or email me at the bakery. Anyway, I hope you like it. I decided to forego music this time and just add commentary. Nothing witty, strictly business.

Hey everybody. This is the same kneading and folding video as before, but with Spanish subtitles for the commentary, thanks to fellow FreshLoafian, Joe Martello. I have an Italian and German version in the works, and am looking for someone to transcribe it in French. If you're interested, I can send you the English version in Word, then you can put the matching French sentences underneath the English. Thanks.

Hi there,

Same Ciabatta video, different music. Let's just say all musicians aren't crazy about having their music in baking videos. OOps. -Mark
