A bottle filled with vegetable oil, be it sunflower or olive, can certainly be found in every kitchen.
However, many cooks make a critical mistake in such a simple process as opening that very container.
For this reason, you should not expect the oil to flow in a thin stream.
To achieve this effect, you should first unscrew the lid and then carefully tear off the ring with the disk attached to it.
A hole with cut edges will open in front of you. This is where you should push the ring, and the disk should be pressed tightly against the hole, as if sealing it.
At this point the operation can be considered complete.
Now you can safely tilt the bottle of oil - its contents will flow out in a thin stream.
Thus, a small detail that most housewives simply throw in the trash can can make the process of cooking much more convenient.
