What each ingredient does
- Salt butter
- Supplies the fat that the churning works into a firm, spreadable mass.
- Fresh milk
- Its cream fat separates and clumps into butter as the churn agitates it.
- Annatto
- Adds a yellow color to the butter.
The step that matters
Wash the butter thoroughly. Buttermilk left trapped in the butter is what drives spoilage, so washing it out with water helps the butter keep better and stay fresh-tasting.
