Salt.

That's a mean answer. But no, seriously, due to my weird eating disorder thing, I've never really had any topping besides salt and butter on my popcorn.

I think I had chocolate melted on it once. I didn't like it that much?

Cracker Jacks are okay so I guess strictly there are a couple things I can tolerate. I just don't have experience with it.

I don't think I'd want to use any sort of spicy topping or anything like that though.
