Question

When rice is boiling over, why do the bubbles immediately go down when you lift the lid?

Answer 1

Because lifting the lid lets out heat and cools the whole thing down. Less heat, less steam, less boiling, less bubbles. Wash your rice before you cook it to get all the starch off and cook on a lower heat, then you won’t have to lift the lid, which is better because you want as much of that moisture to stay in to cook your rice
