My other BBA bread from last weekend was the Potato, Cheddar, and Chive Torpedo from the Grace Note chapter at the back of the book, a recipe from Tim Decker,one of Reinhart's bread apprentices. The potato part of the name is from mashed potatoes and water from cooking the potatos in the dough, making it a very soft, tender bread. The chives also go in the dough, but the cheddar is sliced thinly and rolled up in the dough to get a spiral, and the loaf is slashed so that the cheese can also bubble out during baking.
A barm is used but there's added yeast as well, making the barm a flavoring agent. The most confusing part of the recipe was another of those "dough should be tacky but not sticky" instructions for the kneading process, this time saying "very tacky". I maintain that tacky means sticky in this context, so finding the line for these breads is tough. The other note on the recipe is that I don't see how the weight and volume measures for the chives can both be correct--for my half recipe I should have used 1/2 ounce or 2 tablespoons of chives per the directions. I started with the weight and realized I'd have well over 1/4 cup of chives if I included all I'd weighed out. I ended up putting in about 3 tablespoons or so.
The dough rose enthusiastically on both rises--the barm plus the yeast gave it plenty of lift. I nearly burned the loaf--it got to nearly black on the first interval of the hearth baking, though the internal temp was still low. I covered it with foil to keep it from further darkening, and the finished bread was just very dark brown.
Taste results: it's a bread with that ultra soft potato-bread texture, not a favorite of mine. It had nice crumb, and a very crisp crust from the hearth baking--almost too much with the very soft interior.
