I always threw away the oil cap: a colleague explained to me what it was actually for

This cap has always infuriated me because sometimes you have to pull it hard and quite abruptly, which causes oil to spill. And sometimes the ring breaks, making it very difficult to open the oil. But not so long ago, I discovered why this is really necessary.
Now I’ll tell you everything in detail. The point is that the plug needs to be put back in place, but before that, you need to turn it over.

After that, press the cap inside the bottle so that it’s fixed between the slots.

This gap allows you to measure the oil, meaning it will be poured in a thin stream. If you often cook with oil in small bottles, you’ve probably noticed that there’s a plastic ring under the cap of your oil bottle. While you might think it’s good to throw it in the trash, you’ll find out its usefulness in this article.
