I can't drink buttermilk unless I add a little sugar, but it is great for baking. I use it to thaw out chicken, it makes the chicken more tender and moist. Buttermilk helps the coating stick for frying chicken or making Southern chicken fried steak. We love buttermilk pie and I have a super simple delicious buttermilk chicken recipe that doesn't taste like buttermilk.
I cook for the youth at church twice a month and the teenagers ask for the buttermilk chicken. Maybe the rest of the food I make is so bad the buttermilk chicken is the best alternative! LOL!
