Don’t get me wrong, if you have a good jam or preserves it’s totally fine on a sandwich, and I wouldn’t turn my nose up at it. However, peanut butter doesn’t really need the help, and the extra sweetness from jelly is totally unnecessary. Toasted bread and peanut butter is all you need for a quality simple sandwich.
It’s actually really, really good. I tried it recently. It’s very reminiscent of Thai dishes to me that use peanuts, weirdly enough.
I put peanut butter on both sides and pickles in the middle. Works best with spicy pickles, IMO.
It’s a tasty sweet and savory sandwich.
