Mostly not picky anymore but oh how I hate raisins or grapes in curry or any savory dish. Yuck, yuck, yuck. Really picky about fruit in anything, apple in mulligatawny and in chicken salad eew.
But the Mexican fruit salad that has mango, pineapple, jicama, orange and ONION and crumbled cheese? I love it and nobody else in my household does.
I think (think, not know) that they are in recipes here because a lot of our Indian food is by way of England's Indian restaurants, which are sort of a cuisine unto themselves. So for all I know they could have started as a joke, but it's persisted if so. Someone must like them.
