“You must keep opened ketchup in the refrigerator.”
I agree, and the same goes for mayo, even before it’s opened.
Actually, I store almost everything that’s been opened in the fridge, including bread, nuts, seeds, etc.
I just read that William “Refrigerator” Perry, stored everything in his stomach!* ;-o
