What each ingredient does

Oatmeal
Its starch thickens the liquid as it cooks, giving the porridge its body.
Boiling water
Hydrates the oatmeal and carries its starch into the liquid, where boiling thickens it.
Sweet cream
Adds fat and richness, softening the flavour and mouthfeel of the porridge.

The step that matters

Boil the strained liquid until it thickens. Oat starch only thickens fully when it is brought to a boil and cooked, which swells and sets the starch granules. Stopping too early leaves the porridge thin, while adding cream before thickening can dilute the starch network.
