Chouette22 posted a couple of weeks ago pictures of her Zopf (http://www.thefreshloaf.com/node/13045/hello-switzerland-celebration-bread-and-zopf). In a reply to my post she mentioned that eggs in this bread would make it dryer or stale faster. This motivated me to experiment with my recipe, with the goal to have at the end a fully understood, easy to use and "Americanized" recipe.

To have a solid and accepted expert on my side I used Dan DiMuzio's book, "Bread Baking" to support my testing. On page 138 he defines rich dough and the effect of fat, eggs and sugar in dough. This was a good start as Zopf has all this ingredients in it. Sugar seems to be the least influential with just a little bit more than 2%, but butter (11%) eggs (14%) and to some degree milk(fat) certainly do have an impact. I also wanted to see what the difference between AP and Bread flour would be.

Zopf is the favorite bread of my younger son, so he was very supportive of this idea. He promised his friends in school to bring an entire loaf for lunch and that this bread would beat every other dad's bread. I don't know how many other dads of his friends are baking but I like that it is embedded in him that not only moms are baking and cooking.   

Using my usual recipe I had to adjust the hydration significantly using AP flour otherwise the dough would have been too wet to braid. The final result was ok from an appearance perspective but did taste too much like "normal" white bread and with the additional flour was also much dryer.

Not adding the eggs was a little bit trickier. Eggs are contributing to the hydration but also add fat and strength to the dough. I decided to substitute 75 % of the egg weight with ¾ milk and ¼ water. The dough turned out wetter than usual and I had a difficult time to roll the two strands for braiding. The final bread had less oven spring and turned out a little bit less roundish than usual. The crumb was denser and whither in color. The taste of the bread was even more like white bread.

It seems to me that adding eggs makes Zopf heavier and gives it the crumb structure I like. It also allows for more liquid without impacting the final result.

I will stick with my ingredients but have changed the process to make it easier to assemble the dough. First I add butter, salt (to make sure I don't' forget it again) and brown sugar, zero out the scale, add hot water to soften the butter, then the two eggs and with the cold milk I get to the correct total amount of liquid to balance the varying weight of the eggs. After that I add the flour and the yeast and knead 3 to 4 min on speed one and another couple of minutes, depending on how the dough develops, on speed two of my KitchenAid. 3 stretch and folds with 45 min rest, after the 3rd st&f I divide the dough, braid it and proof for 20 min. Bake for 25 min at 375˚F (convection). The bread should reach 200˚F interior temperature.

I made this bread from Salome's formula a couple months ago. At that time, I couldn't get good quality hazelnuts, so I made it with walnuts only. It was very good tasting, had amazing keeping quality and was excellent after having been frozen.

A new crop of very good tasting hazelnuts finally appeared in my local Whole Foods Market, so it was time to make this bread again. Salome has posted this bread on her own TFL blog since I first made it. She made her bread using a rye sour rather than a wheat flour levain. This sounded like a great idea, so I did it.

Notes on Ingredients

You may note that I have increased the flour for this bake. Maybe my potatoes had more water content or my flour had less. (Or my water was wetter?) In any case, the dough was even gloppier than previously as I mixed it, so, after giving it a good chance to develop but still having medium-consistency batter in my mixer bowl, I added 100 gms more flour. The ingredient list reflects this.

At this point, I'm not sure what to recommend to others except to not add “too much” flour. This is supposed to be a very slack dough. Alternative methods I would consider would be to hold back some of the water and add water as needed (rather than flour) during mixing. This has the advantage of not throwing off the percentages of other ingredients relative to the flour. Another related solution would be to plan on using the “double hydration” technique often recommended for very slack doughs. This entails initially mixing with only 2/3 to ¾ of the total water until the dough has developed some (gluten) strength, then adding the remainder of the water and mixing until it is incorporated.

Procedures

1. The night before baking, activate the rye sour by mixing 20 gms starter with 100 gms of water and 80 gms of whole rye flour. Cover and ferment for 8-12 hours.

2. The next day, roast, steam or boil the potatoes. Peel them.

3. In a large bowl (or the bowl of your mixer), dissolve the rye sour in the water. Add the flour and potatoes, mashed or put through a ricer and mix to a shaggy mass. Cover and let rest (autolyse) for 30 minutes.

4. Add the salt and coriander and mix to moderate gluten development. (10-13 minutes at Speed 2 with a KitchenAid)

5. Transfer the dough to a floured board and, with well-floured hands, stretch it to a 14” square. Distribute the nuts over the dough, roll it up and knead for a few minutes to evenly distribute the nuts throughout the dough.

6. Form the dough into a ball and place it in a lightly oiled large bowl. Cover the bowl tightly.

7. Ferment the dough until doubled in volume with stretch and folds at 30, 60 and 90 minutes.

8. Transfer the dough to a lightly floured board. Divide it in two equal pieces and pre-shape each into a log. Dust with flour and cover. Let the dough rest for 10-20 minutes.

9. Shape each piece as a bâtard and place them, seam side down, on a linen or parchment paper couche.

10. Cover the loaves and proof them until they have expanded to 1.5 times their original volume.

11. 45-60 minutes before baking, pre-heat the oven to 430F with a baking stone and your steaming method of choice in place.

12. Transfer the loaves to the baking stone and bake with steam for 10 minutes, then another 20 minutes without steam. If the loaves are browning too fast, turn the oven down 10-20 degrees.

13. Bake until the internal temperature of the loaves is 205F.

14. When the loaves are done, leave them on the baking stone with the oven off and the door ajar for an additional 5-10 minutes to dry the crust.

15. Remove the loaves to a cooling rack and cool completely before slicing

I sliced the bread and tasting it after it was completely cooled. The crust had softened somewhat but was still crisp. The crumb is moist but pleasantly chewy. The nuts are soft but provide little pops of nuttiness. This is particularly true of the hazelnuts, which I roasted longer than I usually do. The overall flavor is outstanding. There is more of a sour flavor than my previous bake of this bread, presumably due to the rye sour. There is no discernible rye flavor, but it does add to the overall complexity of the flavor as well as to the sourness.

I do prefer this version with the walnuts and hazelnuts and with the rye sour. 

I'm taking one of the loaves up to San Francisco tomorrow to nourish 3 of my siblings who otherwise would be suffering with only bread from Acme, Boudin, Semifreddi, Arizmendi, Tartine, Noe Valley, etc. to eat. <sniff>

And let's slice them ...

 Now I found something ... 

And this ...

                                   Lovely crumb to me                                        but this is slightly on the dense side and gummy, why?

A wake-up call:

I recall when I was mixing my starter in the water for the final dough, I felt tiny little lumps of dough in my hands but I was unable to break them up because they were too many.  I used a trick that I learned from making custard when there were lumps - by pushing the starter through a sifter, I managed to get rid of most big lumps, but there were still many very tiny ones.  I got tired of trying to get rid of them, so I proceeded as normal.  Those lumps would most likely have been formed during the 2 hour final levain expansion (see my post here for details of Chad Robertson's sourdough timeline) - I did not mix the starter thoroughly with the flour and water.  And these lumps, however small, became the gummy part of the crumb!  (I may be wrong but that's what I think it was.)

A myth: The longer the fermentation, the better it is for the sourdough.  No, it depends on how time is spent, not how much time there has been.

With this sourdough, I learned something new.  What happened was when I was trying to get rid of the lumps, my hands were stirring the starter in the water for quite a long time (15 to 20 minutes at least).  I had never seen so many bubbles appearing in the water as if all of the wild beasties were woken up from their sleep and were doing their morning exercises.  This would not have meant anything to me, had it not been the fact later on that the fermentation seemed to have advanced in quite a fast pace even though the dough temperature was under 20C / 68F.  (I wish Debra of the Frankendough could help me out here.)

Anyway, with the fermentation kicking along, I decided I wanted to do an experiment, and that is, to really work the dough with my stretch & folds in such a way as to really build the dough strength.  I dipped both of my hands in water (to prevent sticking) and, with one hand pressing the centre of the dough, the other hand grapping a corner of the dough and folding onto itself, I stretched & folded the dough quite vigorously for at least 30 to 40 times at each set of S&F's until the dough felt elastic.  I did 3 sets of S&F's within one and a half hours and within that time the dough expanded quite a lot.  In normal circumstances I would have done a 4 hour bulk fermentation as in my post of Chad Robertson's country sourdough; but in this instance, I decided one and a half hours were enough (the dough temperature stayed under 20C).  I divided the dough into three pieces and pre-shaped them twice as they were very soft and even though I pre-shaped them to very tight balls each time they relaxed and spread out completely.  I shaped them to tight batards and only proofed for half an hour, compared to 2 hours previously when I did my Chad Robertson's.  Retardation was only 9 hours.

This morning before I baked them, the doughs were as flat as pancakes, but in the oven, they rose like hills:

What I learned in this bake is that the dough strength (built up from the vigorous stretch & folds) helped in the volume (the oven spring, the open crumb, etc).

Time for some food,

And pack up the rest,

p.s.  The minor variations I made in the formula here compared to the one in My Imitation of Chad Robertson's Country Sourdough were: (1) 72% hydration; (2) 5% of total flours in rye flour; and (3) total dough weight 3 kg.
