Dave, some of these issues are mine too. If we are to proceed, we need to follow recipes, at least at the beginning. I typically think of meals, look up recipes (keeping in mind what's seasonal), and build my shopping list based on the recipes I will be making during the coming week. Perhaps we could post a weekly shopping list, with amounts of each item, for each experiment? If this is done well in advance it will give everyone the chance to have the ingredients on hand, and if something is hard to find, there will be enough time to track it down or figure out a substitute. Shall we try for weekly? Or bi-weekly? On a specific day if possible, for ease of planning? I'm in. (Every other week might work best for me until outdoor domestic chores end. But weekly would work too but I may miss a week here & there.)
