So what you need to do is add some "tang" to your milk! It's super easy. Just add 1 T of lemon juice (or white vinegar) to 1 c milk and let it sit for about 5 minutes. ta da ~ buttermilk!
Another substitution I've used for buttermilk is to add about 1/4 c milk to 3/4 c plain yogurt.
Either work well; just use whichever you have on hand.
I do fully stand stand by the lemon juice and milk thing.
While doing vegan recipes that called for it, I used the same approach with my Rice Milk..you don't notice a difference unless it's something like biscuits..then the only difference is color.
as for the yogurt, wouldnt greek style yogurt be a better way to go on that one?
bring in more of that Tang?
