Most people close the oven door the moment they’re done using it. It’s automatic. You cook, you turn it off, you shut the door, and you move on. There’s usually no reason to leave it open — and definitely no reason to place anything inside it overnight. Which is exactly why this habit seems so odd. Because some people do the opposite. Instead of closing the oven and forgetting about it, they’ll place two lemon halves inside, leave the door slightly open, and let it sit there until morning.
No tray. No cleaning spray. No obvious explanation. Just two lemons in the oven overnight. And for people who swear by this trick, it’s not random at all. It’s intentional enough that they keep doing it — even though, at first glance, it looks like one of those oddly specific little kitchen habits that shouldn’t make much difference. But apparently, it does.
And once you understand what problem it’s actually meant to help with, the whole thing starts looking a lot less strange.
