Another good spicy/sweet combo is this cajun trail mix that has like spicy stick and nuts and sweet candied peanuts and salty stuff too, it's one of the best mouthfuls when you take a handful and get a bit of it all. Party in your mouth!
I can't stand spicy, sweet, and sour. I absolutely LOVE everything (and I mean everything) salty. So I have to say sweet and salty, just remove the sweet :')
