I've been keeping a low profile recently doing the same old, same old things. Mostly minding my own business and occasionally commenting on baguettes and not much more. Needed a break. But my wife recently piped up and asked if I would make a potato bread. There's a first time for everything, I suppose.
Jeffery Hamelman's potato bread formula in his book Bread uses commercial yeast. Around these parts, with few exceptions, that just won't do anymore. Hence, time for an alfanso-style remake. And a search of the internet seemed to indicate that there was no prior lone wolf out there who made these as baguettes before me. So I'll assume the mantle for now.
Using the Hamelman "standard" of 15% pre-fermented flour, I made a 2 step (actually more from multiple previous leftovers) 125% hydration liquid levain, using 75% bread flour and 25% rye. By the end of the final build the thang was gurgling away with big frothy bubbles, something any mad scientist would have been proud of. FYI - no IDY was harmed in the making of this bread! The roasted yellow potatoes were peeled, cubed and baked in a 425dF oven for 30 minutes. Then riced. 25% of total flour.
I made the mistake of autolysing just the flour and water, which comes to about a 55% hydration - not very accommodating for incorporation of the other ingredients. And something I won't repeat again. Because of the extra effort to get the levain, potato and salt sufficiently ready for French Folds, I did a total of 400 FFs, with a 5 minute break in between to let the dough relax a bit, now the standard M.O. for me. Letter Folds, totaling three at 40, 80 and 110 were easier with each set as the dough became more comfortable and relaxed as it rose.
An all-day sleep in the refrigerator prior to a late night divide, pre-shape and shape. The dough was incredibly compliant and soft - so easy to work with. As this is a 63% hydration dough, I was conscious of ensuring a good seal. Onto the couche, and tucked back into the refrigerator for an early morning bake. 450dF oven, 14 minutes of steam, 14 more for the baguettes, and a 4 more with 2 additional minutes venting for the batard.
The bread itself is soft and light with a surprisingly not-too-forward potato taste. Thanks to the potato, the bread takes on a lovely rust and golden color. Not a particularly open crumb - on the baguette, but I'm past those days now where that is a be-all and end-all qualifier. A good addition for my recipe box.
700g x1 batard, 400g x2 baguettes
Crumb shot added for those few (and you know who you are!) perversely interested in what's going on in the innards of these beasts. I don't know what a potato bread should look like inside, tight or open, but at 63% hydration plus the potato added to the flour, it would seem as though it should be somewhat dense. A pan de cristal it is not!
