Let Peanut Butter Do Its Own Work
Peanut butter is a rich source of calories, and you don’t have to read the ingredients section to know that it contains a lot of fat and oil. If you use peanut butter regularly, then you know that the oil sort of announces itself as it often separates from the butter.
The most common way to get back the even mixture is to stir the contents of the jar. But that just seems unnecessarily tiring when you can simply flip the bottle upside down and wait for the contents to subside. The oil still separates, but upon turning the bottle back, it will move through the butter and mix itself.
