Oil isn't supposed to separate out of peanut butter! Peanut butter is something you're supposed to be able to forget about in the pantry, until a niece or nephew comes to visit and wants a PB&J sandwich. My jar of peanut butter is as old as this house, and it's never needed stirring!
Church food is usually from the Food Bank. I still get food from those some winters! Sometimes you can sneak into the ones in nicer neighborhoods, where they have things like cookies and pudding cups. I hope your mother didn't let you wear your Martin Luther jersey to the Catholic food pantry line! 🤣
