<<Disclaimer: Verify this information before applying it to your situation.>> Hi, Have had a few questions about a suitable replacement for the buttermilk in this recipe. I would use Vance's powder milk replacement, but would add about 1/2 t. of vinager each time I make a recipe with the mix to replace for the tartness of the buttermilk. Please, if you have tried other solutions with success, do tell me and will make a summary. Mireille
