Let's start a project. Ready? Ok. Take two cups of all-purpose flour, two cups of warm water, and a tablespoon of yeast. Shake them all together in an old yogurt container or a big Mason jar, put the lid on tight, and set them on the counter. Now walk away.
We'll be back with the next step on Wednesday. In the meantime, if you happen to have some local rye kicking around, say from a grain CSA, grind it into flour. You'll need that for what comes next—that, and some poppy seeds and caraway. See you then!
