What version of the Bible are you reading, anyway?
Here's the ORTHODOX way to eat Peanut butter: PBJ Sandwiches MUST be eaten on WHITE Bread which makes smooth PB preferable but there is grace for chunky--eternal destination not at risk if using chunky. Grape jelly is the ONLY acceptable jelly to anoint the PB with--eternal destination is in serious question if you deviate on this point. The sandwich MUST be somushed together before eating. Whether with or without crust is a personal conviction -- you will not lose your salvation for either option.
As for Biscuits: It depends on whether one is eating a DROP biscuit or a CUT biscuit. DROP biscuits must be properly buttered and blessed with strawberry jam--or, way more betta is fig preserves...food fit for the Banqueting Table, my friend! CUT biscuits are for holding slices of country ham or as a base for sausage gravy.
I hope I have helped you avoid eternal fire!
