What each ingredient does
- Oatmeal
- Its starch thickens the water as it cooks, giving the gruel body.
The step that matters
Mix the oatmeal with cold water to a smooth paste before adding boiling water. Starch granules clump into lumps if dropped straight into hot water. Mixing them into cold water first disperses them evenly, so the gruel thickens smoothly rather than forming lumps.
