Its function is to perfectly dose the oil.
Press well on the part that you put in the oil bottle and thanks to the three small slots you will obtain a perfect dosage when using it.
It’s true, this little piece that we normally remove and throw away, if you put it back in the bottle as I explained previously, will allow you to enjoy the oil by measuring it perfectly, and when you will have to put it in the stove, you will no longer have to be impatient to want to serve a little. The oil will sort in small doses for the three slots and you will be able to use it without waste.
You will never use more than you need.
Thanks to this ingenious part that is inside the oil bottle and which you find immediately when you open the cap, you will never add more oil than you actually need for cooking.
This is a very useful mechanism to avoid wasting oil and use it in the appropriate quantity. Now you will no longer throw away that oil bottle cap and you will definitely use it because it will save you money.
