I've been baking biscuits since I was a little girl. It is one of the few recipes that I know so well that I've begun to play around with new combinations of flavors and ingredients. The most recent iteration includes some tangy sourdough starter. I prefer to use active starter for this recipe, but it does work quite well with discard starter too. Play around and see what you can make happen. Your family will happily help you fine-tune your version.
