Which item absorbs cooking oil fastest salt sugar or flour?

* Surface Area: Flour has a much larger surface area than salt or sugar due to its fine particles. This means there are more points of contact for the oil to be absorbed.

* Porosity: Flour is also porous, meaning it has tiny spaces within its structure. This allows oil to penetrate deeper into the flour, leading to faster absorption.

Salt and sugar, while they can absorb some oil, have a much smaller surface area and are less porous.
