A sandwich is a structural construction and a peanut butter and jelly sandwich, while sound from a culinary perspective, is a mess to eat. The jelly squirts out the sides, peanut butter gets all over your hands, the bread is often too soft. So I'm trying to address these constructional issues. The peanut butter is a slurry. I've taken regular, creamy, no-sugar added product and added peanut chunks at about a 50/50 mixture. This results in a thickened paste, much less likely to ooze.
