I think it was last week when @Shelby was making some marinated eggplant which got me thinking of caponata. I was shortly sucked into this great thread on the Cooking and Cuisine of Sicily. Gotta go back and finish re-reading that one before I get sucked into something else !
Edited to add: If you really want to go down a rabbit hole, do a search for "Cooking and Cuisine of" and you will find a wealth of Italian regional cookery threads started by @Kevin72. So good!
