user: Provide instructions on making a peanut butter and jelly sandwich

assistant: Making the perfect peanut butter and jelly sandwich is part art and part science. One must must be judicious in the quantity of ingredients while ensuring proper coverage to ensure each bite is equal to the one before and after it. Here, both measurement and distribution of ingredients serves as the scientific aspect of constructing your delicious and timeless lunchtime meal. Jars of peanut utter suggest a serving size as 2 tablespoons, which, when applied to the critical soft white bread, may prove too much to hold and cause soak through or tearing of the bread. We think 1.5 tablespoons is the proper amount to ensure there is coverage of the bread slice to the crust without compromising the integrity of the bread. Jelly application is even more precarious, as it holds more fluid and can soak through the bread quicker; equally, jelly has a tendency to congeal. To ensure proper application, heat the jar of jelly closer to room temperature if refrigerated, then apply using a clean butter knife or small spatula. Again, one must ensure it reaches to the crust and is evenly distributed. Once you have complete coverage of peanut butter on one slice and jelly on the other, place the peanut butter side of the first slice on top of the upward-facing jelly slice. This ensure none of the jelly slips or drips. Once together, gently compress the sandwich. Slice delicately from one corner to the opposite corner. Gently press the crust edge of each triangle, and plate for serving.
