Over the years I've made modifications to the Commons Bread. Recently I've wanted more fiber in my diet but I still prefer the taste of the white flour over whole wheat. Psyllium husks seem to do the trick quite nicely. I've also started to make labneh, or yogurt cheese, and used the whey in the bread. I found that it changed the texture of the bread really nicely, and I even feel like it even keeps the crumb of the bread moist for longer. Since I don't always make labneh or have whey on hand, just plain yogurt does the same thing.
SLOW
Experience cook 4 hours
Novice cook 4 hours
3 cups flour (450gr)
¼ tsp instant yeast (yes, really, that's all!)
1¼ tsps. salt (12gr)
1½ cups water
½ cup yogurt or liquid whey
1 tsp psyllium husk powder
Mix the flour, yeast, and salt in a bowl. Stir in the water and yogurt to thoroughly blend into a very wet dough that'll look more like a sticky batter. Cover the bowl and let it rest in a warm place for at least 12 and preferably up to 24 hours. It’s ready for the next step when the surface is dotted with bubbles. It is crucial that the dough be kept warm, otherwise the little bit of yeast won't be able to propagate in your dough - if you don't have a warm place, put in the cold oven and turn on the light; this should keep it plenty warm to rise. If you don't have a warm place at all, the key is to watch for the little bubbles on the surface, which will take longer to appear in a cold place.
Flour a work surface and dump the dough out onto it, cover and let it rest for 15 minutes.
Meanwhile, layer a bowl with some parchment paper - when the dough has finished rising you will pick up the whole thing to deposit into your hot dutch oven.
Using only enough flour to keep the dough from sticking to your fingers, shape it into a ball and deposit it into your parchment-lined bowl. Cover and in the same warm place, let rise for about 2 hours. When ready, the dough will be more than double in size.
Put a large cast iron pot or Dutch oven (cocotte) inside to heat (I use a 1 3/4 quart CorningWare dish) and turn on the oven to heat to 450°F\230°C.
When the dough is ready, remove the pot from the oven, lift the parchment-lined dough out of its bowl and into the pan. Shake the pan to settle the bread evenly. Cover with the lid, and bake 30 minutes. Remove the lid, and bake another 15 to 30 minutes, until the loaf is nicely browned. Cool on a rack.
