My dad drinks buttermilk. I've seen him put white beans on his chocolate cake (mom's home made one at that) and wash it down with buttermilk.Totally forgot about this thread, so this is a bit behind....
My grandfather drank buttermilk. Not a chance I could do it. Excellent way to become bulimic if you're so inclined. Pukeville USA.
He once paid my sister and I each 50 cents to drink a glass of buttermilk (1968 when 50 cents went a lot further). We talked him down from a 8 oz. to a 2 oz. glass. That's still the hardest 50 cents I've ever earned. She didn't finish hers and only got 25 cents.
I'm baffled that it tastes so nasty but can be used to make some of the best cornbread and cakes.
