It is one of the kitchen tricks.
It is said that whatever we cook in pressure cooker , we must put a spoon along with it.
No .... No ..........
Spoon will not get cooked. !!!!!!
Because of pressure , there forms bubbles when we put rice or dal to cook using pressure cooker .
This results in seepage of water from pressure cooker.
If we put a spoon along with rice or dal ( with water ofcourse. !!!! ) , it stops the water from coming up.
There by it reduces the pressure building up inside pressure cooker.
Some people put 1 spoon of oil alongwith cooking substances inside pressure cooker. Reason is the same.
By doing this , the moisture present inside the substances will not get escape and there will not be water seepage .
