I don't eat bread, but no... people were talking about putting it in a bowl.
PB&J really isn't that much of a thing in the UK, so whilst it may sound strange to you that I don't really know how much of each, it's not something I was brought up doing.
Lol you literally just dump pb (3 tablespoons? 4?) in a bowl and garnish with the jelly of your choice (strawberry is mine)...maybe 1 tablespoon. Try it once.
