First, you must spread a thick layer of peanut butter onto the white part of a slice of bread. You can only spread the peanut butter on the white part, and the white part only. You may only spread peanut butter on one side. Spreading peanut butter on both sides will provide an inferior sandwich. Next, you must spread a thick layer of jelly onto the white part of a slice of bread. You can only spread the jelly on the white part, and the white part only. You may only spread jelly on one side. Spreading jelly on both sides will provide an inferior sandwich. You cannot spread jelly onto the same slice of bread onto which you have spread peanut butter. Also, you cannot spread peanut butter or jelly onto more than one slice of bread, as this will provide an undesired excess of either ingredient. Additionally, only peanut butter and jelly can be spread onto these slices of bread; no other ingredient will suffice, and no substitute can be used in a sandwich that is to be legitimately recognized as a peanut butter and jelly sandwich. Likewise, only bread may be the substance upon which the peanut butter and jelly are spread, as anything else does not fit the standards of a peanut butter and jelly sandwich; if the peanut butter and jelly are spread onto a culinary medium that isn't bread, the meal at hand simply is not a peanut butter and jelly sandwich. Once you have accomplished spreading a thin layer of peanut butter onto the white of one side of one slice of bread, and likewise has been accomplished using grape jelly on a separate slice of bread, you must match the slices of bread up to each other, forming a peanut butter and jelly sandwich. In this scenario, the peanut butter-covered face of bread must be facing the jelly-covered face of the second slice of bread so that the peanut butter surface touched the surface of the jelly. The surface of the peanut butter is not allowed to touch a jelly-less substance of bread, resulting in the jelly facing outwards, and likewise applies to the jelly. If a substance is found facing on the outside of the sandwich, the product will not be accepted as a peanut butter and jelly sandwich. The side with peanut butter and the side with jelly on it must match up and stick together to form one solid sandwich.
