no buttermilk powder, how do I substitute?
Trying your lemon loaf in the segment on l6 lemon desserts. I know how to make buttermilk using lemon juice, vinegar etc, but I don;t have nor seen buttermilk powder. In the recipe for the lemon loaf there is 1 cup of water, do I use buttermilk instead? Thanks Debbie North Van BC Canada
