Please don't jump all over me, but there are a few recipes that start with Bisquik. I was wondering if anyone has experience substituting any other general purpose baking mix suck as Krustez or Morrisons. Before you ask, I don't use it for bisquits.
Most baking mixes are just four main ingredients - flour, baking powder, salt and shortening (plus a bunch of preservatives, dough conditioners, etc). Some homemade mixes also add powdered milk, although most commercial mixes don't contain that ingredient.
Most are interchangeable.
