Ingredients
Directions
Prepare the milk
Boil the morning's milk slowly until reduced by one-fourth, stirring constantly.
Cool the milk until cold in warm weather or leave lukewarm in cold weather.
Cover the milk with a cloth tied over the vessel until afternoon.
Repeat the process with the evening milk and mix both together.
Churn the butter
Add 2 tablespoons of morning's buttermilk to the mixture.
Churn the mixture in the morning, adding cold water as needed while churning.

What each ingredient does
- Milk
- Provides the fat and protein that separate into butter when churned.
- Buttermilk
- Adds live cultures that sour and thicken the milk before churning.
The step that matters
Churning with cold water. Adding cold water as needed while churning helps the fat globules clump together into butter. Water that is too warm can soften the fat so it will not gather properly.
