What each ingredient does
- Salt butter
- Provides the fat base that gives the finished butter its richness and body.
- New milk
- Supplies the water and milk solids that churning separates into butter fat and buttermilk.
- Annatto
- Adds a yellow colour to the butter, as the record's small quantity suggests a tint rather than flavour.
The step that matters
Churn the mixture for about an hour. Churning must continue until the fat globules clump together and separate from the buttermilk. Stopping too early leaves the butter soft and milky, while over-churning can make it grainy.
