Finally – after searching for a long time -- found your really good biscuit mix; thank you! I hate to use Bisquick because the ingredients on the box note aluminum in the baking powder and partially hydrogenated oils. Don't want either of those ingredients in my food! I use only aluminum-free baking powder (easy to find – Argo is one brand). If I don't have buttermilk on hand, I make it by adding 2 teaspoons of vinegar to 3/4 cup of milk. It should be white vinegar; used organic cider vinegar once – interesting taste! Sometimes, I make this marvelous recipe with regular milk and a few spoonfuls of plain yogurt (the acid activates the baking powder). I use olive oil, and, sometimes, coconut oil, just for a different taste. Have made this recipe with orange juice instead of milk (the juice's acid gives the kick to the baking powder). I cut the sugar back a bit. Sometimes, I add yeast to the liquid and let it rise (no kneading). Gives a "bready" flavor – good for pizza base. I always use a Silpat silicone baking liner – NOTHING sticks to it, not even melted cheese or burned brown sugar. Both daughters want me to will my two Silpats to them, ha, ha! -- Mary in warming up Pennsylvania
