Can you use kefir as a substitute for buttermilk?
Chili for dinner, and my hubs wants to make his mom's cornbread...very southern, no sugar, no regular flour, just corn meal, eggs, buttermilk, bacon fat. Went to the store but no buttermilk. Grabbed kefir and hoping he can use it in a one to one ratio as a substitute? Or do I have to tell him to stop on the way home for the real deal?
