I regret I hadn't photo documented and tasted that yam loaf.  It took much longer rising  (influenced by long rises on the Tartine theme) ending up on the porch overnight, and because that was too cold in the morning, I did some microwave low voltage zaps to it and then when it got to rising, had to tip it out of the banneton (no problem, rice flour) and fold the dough.  It was so full of rice flour (fear it might stick) I ended up holding it under the running tap to wash off the flour.  A few folds in the air with wet hands and I was in business.  Dusted the banneton with more rice flour, plopped dusty rose tightened dough ball to rise.  Covered with inverted bowl.

Excuses, excuses.  I was trying to bake and finish up packing with dog washing, and the hundreds of things to take care of.  At one point I turned on the oven, tossed the loaf in with a pan of boiling water.  With 15 min left to the 50 minute bake (200°C)  I threw myself into the shower.  I heard the timer and hurried dripping wet to pull the loaf out of the oven...  not bad!  Nice spring and not so purple, with a deep brown crust and lovely overall form.  I parked it on the rack and it was still warm when I headed out the door to the airport with bags and dog. (She was the first in the car.)  Called my SIL from airport security to collect the rest of the flour, the loaf and report back what she thought of it.  She's been bitten by the bread bug only recently.  Golly, the crumb colour, I so wanted to see the inside and taste that loaf.  Wish I had a hunk of it now, here in Bangkok with a midnight hunger that could rip open the crustiest of loaves without a knife.  A little butter would also be nice.   :)   

We did get a some food and rehydrated ourselves mid afternoon,  we in transit, Dolly and I, settled down for a long AC nap.  We were so tired.  Now we're awake and I have only one question... when are hotels going to put some decent baked goods in the mini bar?

Working on a oven building project, my first.  About to send off some fire bricks/parts for a wood or gas brick oven and need some input.  

I have to get something into the container at the end of next week for the shipment and need input.  Clay, broken pots and rice hulls will be there.  Tropical, in a camp and half the year is rainy.  Also any steel and concrete works, base and hut are there where I'm building the oven.  Right now my main concern is with the oven itself.  I haven't got the brick or shelf sizes or flue sizes yet.  What I'm needing is the physics, height of openings, chamber, door.  If rock wool is needed what kind and how thick.    thoughts... comments... ideas... where to put a gas flame entrance and if I have to stack 4.5 cm thick shelfs (40cm x 50cm) on top of one another for the baking chamber (for lack of bricks)  does the space present a problem.  

Am I asking for too much time to heat up an oven with a 4 inch or  10cm thick firebrick walls  as compared to one with 2 inch or 5cm walls?  

The drawing I've come up with:    each tiny square denotes 10cm 

 side view  and front view

A is the door opening  

B is the flue opening between baking chamber and chimney  

C is the chamber outer shell (or all the stuff on top of the bricks to seal and insulate then decorate)

D is under the baking chamber (not to forget to insulate)

E is the flue

F  is the flue control (manual) by pushing in and out a slab of fire clay, can be also smeared with a little mud to seal tight after heating chamber  two create a "dead air space"

G  is gas portal waiting for a location

Baking chamber is 80cm wide  x 100cm deep and 35cm tall in the barrel shaped middle.  

Thanks all!

Basically a 1-2-3 Sourdough formula using two fresh baby Rye and Einkorn sourdough starters.  Started respectfully on Friday and Thursday of last week, this is their first loaf.  Last night they had peaked in activity (4 and 3 days old) and I combined:

1)   215g sourdough starter,  predominantly a rye sour 

2)   350g water with 50g Whole Einkorn flour Tangzhong.      Making a 70% hydration dough

3)   600g of flour:  100g fine Rye, 100g Whole Einkorn, 200g fine Spelt, and 200g Organic AP wheat.  (not much strength there!)

   14g salt    14g Bread Spice

Mixed up, covered and let sleep 16°C overnight or 14 hrs.  It did rise about 1/2 so did one set of folds in the morning followed by a shaping.  The dough just seemed to be far enough along at 11 am that no other handling seemed needed.   Banneton rise at 24°C.   

Bake 240°C for 20min with steam pan.  Remove steam, rotate,  reduced to 200°C for 20 minutes.  Inside temp 100°C (212°F)

The No Stir Sourdough Starter

This last week I started a vigorous rye starter by simply pouring water over rye flour and leaving it alone, covering it.  No stir, no mixing, just stand alone at 75°F and watch.  

This time I want to avoid, skip over the stinky bacterial population growth in the starter so I'm pouring sauerkraut juice over flour to see what happens.  Same 74°F to 75°F  temperature.    


  1. Spoon rye flour into clean tall narrow jar.   About one inch or 2.5 to 3 cm. deep.  (I used 30g Rogers whole rye flour)
  2. Pour strained sauerkraut juice gently over the flour.  Should make a top layer of about half an inch or 1.5cm deep.    (I used 40g strained Bick's Wine Sauerkraut)   Do not stir.
  3. Mark the level, time and date with a permanent marker pen.  Cover loosely with lid or plastic wrap and loose rubber band. 
  4. Stand in warm spot 75°F (23.8°C)  out of drafts and danger.  Do nothing but observe but this includes daily removal of cover and noting aromas before recovering.  

That is it.   Just for information my culture growing glass is about 2" in diameter, 5" tall and weighs 178g empty.  The sauerkraut contains sodium as well as vitamin C, wine and sulphites.  The last of which may or may not interfere with yeast activation.  It is not raw sauerkraut juice which might be preferable.  When the starter takes on a beer aroma, it will be fed more flour.

Anyone wishing to participate is welcome.  

Options might include other flours, other sauerkraut juices, other temperatures.  As sauerkraut is fermented around 60°F it might be interesting if a 60°F sourdough starter could be developed (might take more time?)

It's a Spelt & wheat loaf, with rye, chia, and fluffy hemp hearts.  It speaks Italian.

Cranked out a sourdough loaf with a rather slow starter based on the famous 1,2,3 ratio recipe.  Letting the dough retard in the fridge overnight gave it an edge and I didn't have to worry about it.  Set it out to warm up, gave it another fold and rested it in a make-shift banneton lined with a large paper napkin.  Baked it around noon.

The loaf is decorated with a slurry of rye, water, lemon juice, active malt, salt.  A small coffee cup transferred the "rings" from the plate of slurry to the flour dusted loaf.  Scoring could have been a bit deeper but I'll take it.  


150g wheat starter (just peaked) 

285g water

 15g fresh lemon juice

13g or 1 Tbs olive oil


200g spelt flour

150g white wheat flour (I used Antimo Caputo 10% protein) (that's where the Italian comes in!) 

 55g dark rye (Rogers)

 25g hemp hearts

 20g chia seeds

10.5g salt  (2% of 525g total flour)

Mix dough by spoon adding the oil after the flour and seeds have been moistened.  Rest 30 minutes and lightly knead the dough one minute.  Let stand until the dough starts to puff up about a third.  In my case with a weakly yeasted starter, 4 hrs.  First firm stretch and fold followed by another in one hour.  Cover and place in the refrigerator.  

Next morning (about 12 hrs before baking) remove and let dough come to room temp and rise.  When almost doubled, turn out,  degas and fold to shape.  Place top side down in a basket lined with a large flour dusted paper napkin (wow, it works!)  (The dough had so nicely risen before I took notice that I think shaping sooner and letting double in the banneton or tin is also another way to go with this stiff dough.  Pretty easy to manage and not sticky.)

Heat oven to 230°C (450°F)  just before dough has risen enough.  Turn out onto parchment.

A slurry of 20g rye flour, 1/2 teaspoon of active malt (for a dark colour) lemon juice (for stretch) pinch of salt, and water( to make a thick paint) is mixed on a plate.  

Dip the rim of a glass or coffee cup into the slurry and then "print" it onto the dough. Easy!

These make the olympic Rings on the floured surface of the dough.  I got a little carried away adding more rings.

Slash and bake about 40 to 45 minutes turning down to 200°C (400°F) halfway into the bake.  

Inside temp measured 208°F (98°C)

This rye recipe is my Chilean version of my favorite rye ratio recipe using a rye sourdough starter and the addition of chia seeds that increase the dough hydration yet maintain a nice shape.  Use a large Dutch oven for a free form shape. 

I designed this recipe for one narrow tapered loaf pan:   cm: 30 x 11 x 7.5   or   inches: 11 3/4 x 4 1/4 x 3 

It is my basic rye recipe (starter:water:flour) (1: 3.5 : 4.16) plus 6.1% chia (on total flour weight including flour in the starter) plus 4 times the chia weight in water added to the dough.  Also added nuts, seeds and 90g to 100g arbitrarily selected moist rye altus (day old bread.)



The wet:

  • 175g vigorous peaking rye starter  100% hydration
  •  90g  moist rye altus 
  • 812g  water  24°C   (75°F) 


The dry:

  • 728g rye flour  (dark rye 14% protein)
  •  50g chia seeds
  •  17g salt   (2%)  
  •  17g bread spice  (2%)  (toasted crushed mix: coriander, fennel, caraway seed)
  •  17g toasted sesame seed  (2%)

         829g    (total dough so far 1906g) 


  •     4g black pepper  (0.46%)
  • 100g broken walnuts
  • 150g chopped Araucaria Pine nuts   
  • sunflower seeds to line bottom and/or sides of buttered form 



Inoculate (1:5 to 1:10) sourdough starter soon enough to have a vigorous starter when ready to mix up dough.  

Plan to bake in 3 hours from the time you start combining liquids with the flour to make dough.  

Combine liquids and break apart floating altus.   Stir dry ingredients and add to liquids stirring until all dry flour is moistened.  Scrape down sides of bowl, cover, let stand 2 hours.  No kneading ever!  Dough will stiffen as it rests.   (Another order for combining is to add the chia and spices to the wet ingredients and allow to swell 15 minutes before adding flour, salt and nuts.  Not sure if it makes a difference but if you find you're getting a gummy crumb, let the chia soak in the water and swell before adding the flour.)

Smear bread pan with butter and dust/coat with raw seeds, crumbs or flour.  Spoon or plop dough (trying not to trap air) into form or floured banneton.  (The recipe lends itself well to free form in a large Dutch Oven.)  Use a wet spatula or wet fingers & hands to shape dough.  Pile the dough up higher in the center for a nice rising shape.  Sprinkle with seeds and press lightly into dough while making a nice dome shape.  

Let rise about an hour.  Meanwhile heat oven 200°C to turn down to 185°C (365°F) 15 minutes into the bake.  Make a cover for the loaf from a double layer of alufoil or flip an identical pan over the top.  Leave room for loaf expansion.  

When ready dock,  take a wet toothpick and poke about one hole every inch, all over, toothpick deep.  Wait a few minutes and smoothen over with a wet spatula.  Dough is ready to dock when you see the dough surface threatening to release trapped gasses under the surface.  One or two little pin hole bubbles is enough to start docking.

Spray or rinse the inside of foil or empty bread pan cover with water and cover the dough to trap steam during the bake.   Bake for about 40 minutes on the lowest rack, then rotate and remove the protective cover to brown the loaf top.  Finish the loaf in another 20-30 min for a rough total of one hour baking time.  Inside temp should reach 94°C, sound hollow, but I tend to shoot for 96°C or 205°F.   Cool on rack.   Wrap when cold.  

Here is the cold loaf (after 12 days, last 6 in the fridge) and you can see how much the dough rose. The shaped dough would have been rounded under the rim.   There are no nuts in this loaf other than what came from frozen stored altus.

Free form using floured rice sieve:           Oops, I spy a few docking holes!  

Have fun,  I do!    Really proud of that one!

Not being in the Avocado capital of the world but swimming in avocados, I decided to try an experiment using only avos (avocados) for my liquid.  Started with the basics and going from there.  I happened upon some watery thin skinned fruit that I am told are known as "Florida avocados" and thought at first interesting but then reality set in, sure enough... less fat, more carbs and more water.  Hmmm not exactly what I value in an avo but good enough for a cracker experiment and maybe a bread.  

Peeled the avo and diced it into a bowl on the scales.  Added equal weight of rye for a reference point and began to squish it all together.  Went much faster than I thought, and they weren't even mushy avos!  Let that sit for a while to soak and soften lumps wondering about the dough turning brown, should I add lemon or sourdough?  Does one even add leavening to crackers?  Nibbling on the dough, well, it needed something.  2% salt would be about 4.4g on my 220g flour and I had black olives calling out from the fridge.  Half dried chili peppers would be colorful (threads?) and crushed garlic would also be good,  black pepper?  Bread spice?  Cumin?  Curry?  Petunias?  Had to start somewhere.  What makes them puffy? Resting time and hot baking the water in the dough.  

First Run:

220g Florida Avocado     (the watery kind)

220g medium rye flour

2 garlic cloves

10 black olives       (cut from pits, salty)

1 chili pepper         (mine was thumb size and medium spiced)


flour/raw seeds for rolling

oil for 3 sheets of parchment    (1 tsp each sheet, flavoured or not)



Remove seed and skin from avocado and cut into pieces, weigh.  Add equal weight rye flour.  Pinch and mix with hands until it becomes a firm dough and lumps of avocado are well blended into the dough.  Autolyse or allow to rest covered for 30 minutes.  Then arrange on a nice plate photographic piles of pressed garlic, finely chopped olives and a rounded tablespoon more or less finely chopped fresh chili pepper.  Add to dough, forget to make a photo, check moisture, it should be a bit sticky now but still firm enough to roll out, yet soft enough to do so easily.   Rest another 30 minutes.


Divide dough in half,  shape into a rectangle hamberger shape and roll into a mixture of flour and sesame seeds to coat, this helps with the rolling out of dough.   Wrap up one to prevent drying.  Roll out dough as thin as possible between two layers of lightly oiled parchment paper.  Anything squishing out can be cut off and stuck back on in a needy spot under the parchment.   Carefully peel back top sheet of parchment.   Sprinkle with seeds/salt.  Score if desired to facilitate breaking and transfer to baking sheet.


Bake middle of oven at 200°C or 400°F until medium brown, rotate to avoid burning back corners.  Allow to cool on rack.  Break apart.


Flavour tweaking needed.  I found it smelled and sort of tasted like teriyaki beef jerky, a little bitter (I did get it brown) without any sweetness.  I chrunched on half a sheet of the stuff trying to decide my next step.  Maybe brushing the rolled out cracker with honey water or using some sourdough or aging of the dough 24 hrs to bring out sweetness.  Lots of different directions to try.  Tempted to turn down heat a little bit to help dry while baking.


This is an open experiment, all comments and jumping in to experiment and post more than welcome!
