Stick always in the butter dish for room temp and spreadable. Also for frying up stuff. Rest of it, in the fridge.
when the room temp is 30C, that is a bad idea.
“butter: fridge or not” is basically a quiz to find out where people live.
I’ve been doing this since CoOViD. Previously I never used butter because it’s too hard from the fridge and “everyone knows” you need to refrigerate it.
However I started doing a lot more cooking, so it’s always been finished before it goes bad:
- FDA recommendation 3 days on counter
- “rule of thumb” 1 week on counter
- some streamers claim 2 weeks
I’m not even sure what “going bad” means for butter. I have seen it change color so the outside is darker than inside, and threw it out. But ive never noticed an off taste or smell.
