Guava duff is a pudding that behaves like a holiday even when it is only Sunday. Families argue about whether the sauce should be more rum or more butter. Benny cake is the opposite energy: sesame, sugar, a snap, sold in squares that survive a beach bag. Coconut tarts are the Nassau bakery default.
Conch fritters keep the map honest. Not every Bahamian snack is sweet; Arawak Cay exists because fried conch is an afternoon. Rum cake is what tourists successfully export. Duff is not. If you only buy one dry sweet, make it benny cake, not a melted chocolate bar from the resort shop.
