I have a recipe for homemade playdough. The problem is that is needs cream of tartar–since it isn’t available here. I’ve read about white vinegar and/or lemon juice. Would it work as well in this recipe?
I live in Germany where this is not readily available. I do believe that I can get it, but it is usually imported, which is expensive, or at "foreign" (asian, middle-eastern) markets, and expensive.
