Why it works: Milk and cream are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 29,399 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
To Make Butter
Ingredients
Directions
Prepare the milk
Strain the milk into a pan.
Add 1 gallon of boiling water for every 6 gallons of milk.
Dissolve 1 ounce of nitre in 1 pint of spring water.
Add ¼ pint of the solution to every 15 gallons of milk.
Skim the milk when the sun has not heated the dairy.
Churn and wash
Churn the cream twice a week, keeping it in a cold cellar if possible.
When the butter forms, pour off the buttermilk.
Transfer the butter to a fresh, scalded pan.
Pour water over the butter.
Let the butter sit to harden before working it.

What each ingredient does
- Milk
- Provides the fat and milk solids that are separated and churned into butter.
- Cream
- Concentrated fat that churns into butter as its fat globules clump together.
- Nitre (saltpetre)
- Preserving agent that helps inhibit spoilage in the milk before churning.
The step that matters
Keeping the cream cold before churning. Cream that is too warm produces soft, greasy butter that churns slowly, because the fat stays liquid and does not clump into grains. Cool, steady temperatures help the fat solidify so it gathers cleanly.
