When I think of PB&J I think of one made with home made black raspberry jelly. It’s really good and for me is much better than using grape jelly. You really should try this. I ate a LOT of these when I was in school for lunch.
Check out a variation on this which is a Toasted Peanut Butter and Black Raspberry Jelly Sandwich.
Here’s the recipe but I think you already know how to make one. Store bought is ok, but home made is better.
