What each ingredient does
- Oatmeal
- Forms the thick body of the porridge as its starches swell and gelatinize in water.
- Fresh butter
- Adds richness and a smooth, silky mouthfeel as it melts into the hot porridge.
The step that matters
Stirring while bringing to a boil. Oatmeal starch can scorch on the bottom and boil over if not stirred often, so frequent stirring keeps the porridge even and prevents spills.
