Why oil marinate into rice for congee?

Oil is often added to rice when making congee to enhance flavor and improve the texture. It helps to create a silky and smooth consistency, making the dish more enjoyable. Additionally, the oil can carry and amplify the flavors of any added ingredients, such as spices or aromatics, resulting in a richer overall taste. This technique is especially effective in traditional recipes, contributing to the dish's comforting nature.
