in my region it seems there is no merchant who sells buttermilk or buttermilk powder .
i recently saw buttermilk fried chciken recipe from the cookbook ad hoc at home by thomas keller.
so i must dupicate it in my home.
what i can find is heavy fat contents of sour cream (35% fat), heavy cream(38% fat), skimmed milk, white vinegar, and lemon.i think it( 2 tabsp of sour cream plus skimmed milk ) may help but am quiet not sure whether it can really help or not.
could anyone sugeest some good ways of duplicating buttermilk for buttermilk fried chicken recipe?
