He already covered this in the OP. Smuckers says you don't need to refrigerate their jelly, but they recommend it to extend the life and slow separation. Sugar is a preservative, you should be fine.
Peanut butter does not need refrigeration. Never heard of anybody keeping it in the fridge. Jelly and or jam might. See what it says on the label.
Ordinary commercial peanut butter like Skippy and Jif doesn't need to be refrigerated. Natural peanut butter, like what Mrs. TJ buys, separates because of the lack of hydrogenated oil and usually needs to be refrigerated or it will eventually go rancid.
...but on day two your skin will start to blister and peal off.
I think you'd have to keep it a long, long, LONG time for that to happen. I have had a jar of the natural stuff in the cupboard for 6 or more months on more than one occasion. You have to stir it because the oil floats, but I never had a problem with it going bad. On the other hand, it doesn't take up much space in the fridge, so there's that.
I did not know that about mayo, would guessed the opposite but the internet says you're right. HROT is always schooling me.
A bottle of ketchup lasts us a few years, and we never keep it in the fridge. We keep mustards in there, as we have half a dozen different kinds on hand at any given time and we've gotten used to having them there. Usually we just do what the label says. If a salsa says refrigerate after opening, we do; if it doesn't say that, we may or may not do it.
