A couple of months ago I was one of many speakers at a Greater Midwest Foodways Alliance symposium on midwest food traditions; I talked about the food of my German Mennonite ancestors, who passed through the Ukraine on their way to Kansas and picked up some Russian foods not otherwise known to their German coreligionists.
WBEZ now has all the talks available on their site; Cathy2 has the links. I’m in the 5th one, Home Baking II.
