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

You have probably already noticed little plastic tabs on oil bottles several times. Maybe you even ignored them, thinking they served no purpose other than to make opening the bottle more difficult. Well, think again! These tabs have a very real use and can make your life easier in the kitchen. So, before you throw them in the trash, find out why they’re worth saving.
A tab with a dual role
The tab plays an important role in the oil preservation process. It acts as an airtight seal, preventing air from entering the inside of the bottle. Air can be bad for oil because it can accelerate its oxidation and alter its flavor. It ensures better preservation of the oil and extends its lifespan.

Controlling the amount of oil to use
When you want to prepare a recipe that only requires a drizzle of oil, it is sometimes difficult to control the amount that flows from the bottle. As a result, you always end up putting more than you need. But thanks to the plastic tab inside the bottle, under the cap, this problem will be quickly solved.
Indeed, the small ring allows you to partially block the spout of the bottle, and therefore, to more easily control the amount of oil to pour. This way, you can pour this liquid without losing a single drop. Pretty practical, right!?

However, be careful not to press too hard on the tab so as not to push it inside the bottle. To do this, simply press gently and lightly.

Avoiding oil splashes and waste
You’ve probably poured oil into a pan or onto food to cook, when suddenly, accidentally, you squeezed the bottle too hard, pouring too much oil. The result? You end up with oil splashes everywhere, including on your clothes and the hob.

In this case, simply remove the ring and then put it back on upside down to prevent any risk of waste or splashing. This will save you money and avoid this type of accident.
