Why it works: Milk and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
To Make Butter
Ingredients
Directions
Separate the cream
Scald the milk in pans daily.
Let the milk stand for 24 hours.
Skim off the cream into a large covered jar.
Stir the cream daily to prevent a skin from forming.
Strain the cream into a churn and cover the churn.
Churn and wash
In warm weather, move the churn handle slowly to avoid soft butter.
When the handle is difficult to turn, the butter is ready.
Remove the butter with a wooden ladle and squeeze out excess milk.
Add a little salt and work the salt into the butter.
Let the butter sit in a cool place for 3 hours.
Work the butter again.
Wash the butter in cold water.
Store the butter.
Cure and pack
For curing, mix 4 ounces of salt, 2 ounces of loaf sugar, and ¼ ounce of saltpetre.
Work this mixture into the butter.
Pack the butter in jars or tubs.

Shared aroma: 2-nonenal (fatty, green).
Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Its butterfat rises as cream, which is churned into the butter.
- Loaf sugar
- Adds sweetness to the curing mixture worked into the butter.
The step that matters
Churning in warm weather. Warm cream makes soft butter because the fat stays too liquid to gather firmly. Churning slowly keeps the fat cool enough to clump into firm butter, and stopping when the handle becomes hard to turn marks the point where the fat has come together.
