I have a question about the recipe "Whole Wheat Pumpkin Plum Muffins" from em-i-lis. What could be a good substitute for the plums--which are hard to come by for me? Banana?
Banana seems a little off for me. I would say any stone fruit would do and I could see pineapple giving you that "upside down" vibe and then I might a little brown sugar in the bottom.
Apple slices, maybe?
Can you get prunes? They're dried plums. You could soak them or just snip up pieces of the dried fruit.
