A few months ago, as an experiment, we sent some sourdough starter through the U.S. Mail. We previously posted the results from one recipient. The other sample went to Keith at the Successfully Living Simpler blog, and he posted the results. He claims that he made a “mistake” with the recipe, but I would say that he actually made an “invention” by inadvertently mixing two recipes to make these biscuits.
Early in the pandemic, many people simultaneously decided to take up baking, and yeast became almost impossible to find. But a single package of store-bought yeast has now been used to make bread in three different states. And in my refrigerator, I still have the means to continue making it indefinitely.
