Martha Stewart Rockford’s aunt Sally sent me a few wonderful cooking tips a few weeks ago. I haven’t tried them yet, but they’ll be “working for me” soon!
I don’t know if you need “emergency solo meals,” but scoops of Sloppy Joe mixture in a muffin tin, frozen, then popped out into a freezer bag make a great 1-person serving. And on the muffin tin subject, if you freeze your muffin dough (unbaked) in the tins & save them in a freezer container, you can bake them just 5 minutes longer that the regular recipe and they’re bigger/better than the original.
I think the “solo meals” idea would work well for tacos, too, and maybe even for leftover soup. Do you have any great, non-muffin uses for muffin tins?
