Add a drop of 'cooking oil + a few drops of white vinegar' when cooking rice for fluffy and sweet grains

Principle and Method: When you've washed your rice and are ready to cook, add a few drops of white vinegar and a little vegetable oil. Vinegar helps break down the starch in the rice, allowing the grains to absorb water faster without tasting sour. The oil forms a thin film on the surface of the rice grains, resulting in a fragrant, glossy, and perfectly separated cooked rice.
