What each ingredient does

Oatmeal
Provides the starch that thickens into a porridge as it cooks.
Water
Hydrates the oats during soaking and becomes the cooking liquid that softens them.

The step that matters

Boil the oatmeal until it thickens. Oats need enough heat and time for their starch to gelatinize and swell, which is what thickens the porridge. Stopping too early leaves it thin, while overcooking can make it gluey or stiff.
