i'm pretty awful at measuring things, so some things are approximate. particularly the salt. it's a little over 1 tsp. also the measuring is a little weird because it was adapted from a recipe for six loaves. (yes, i really, honestly do use half an egg. i've never tried using the whole thing.) i never actually take the temperature of the water. 105° is slightly warmer than body temperature, so i just run the water across my wrist until it feels a little bit warm.
this makes one loaf.
