peanut butter

This one absolutely turns on what kind of peanut butter you have. Jif/Skippy etc. shouldn’t go into the fridge. It was engineered, for better or worse, to be shelf stable and turns into silly putty if it’s cold. Most “Real” peanut butter separates like a mofo if it’s in the pantry, requiring frequent stirring, and many recipes will never quite be solid enough to spread well. In the fridge, they are much easier to deal with, though my latchkey Xennial ass still prefers the wondrous combination of peanut-like substance and mid-century food science.
