Peanut Butter First

It’s a scientific fact. A while back, I wondered why I always spread the peanut butter before the jelly, so I tried reversing it and spreading jelly first. After months of research, I have determined that peanut butter first is the correct method.

The reason is quite simple: Whichever one is first allows you to wipe the knife blade on the other clean slice of bread, removing the substance from the knife. If peanut butter goes first, one can wipe any remaining peanut butter off the knife. Any jelly remaining on the knife will get washed off in the dishwasher. If jelly goes first, any remaining peanut butter on the knife may or may not get washed off in the dishwasher.

For whatever reason, my dishwasher (and various brands of soap) is not very good at washing/dissolving peanut butter. Therefore, if something is going to remain on the knife, it is better that it is the jelly, which means peanut butter goes first.

Long live science!

Which reminds me that I bought temperature probes to figure out what’s going on with my butter. It’s almost “turn on the furnace” season, so it’s time to start collecting data.
