Have had many peanut butters, and generally love them all.
One of my favorite ways of eating the ambrosia is to mix it with some Worcestershire sauce, finely diced onions (can be sauteed, but generally prefer them raw), spread the mixture on white toast, place several rashers of fried bacon on top, and cover with another piece of toast.
Or you can just put slices of raw onion on the peanut butter. But always try it with the Worcestershire sauce.
If you want to butter the toast first, it is only better.
Worcestershire sauce works amazingly well with peanut butter.
At least IMHO.
