Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Butter, Philadelphia
Ingredients
Directions
Prepare the cream
Set pans of milk in flowing water at 58°F (14°C) for 24 hours.
Skim the milk and place the cream in deep vessels (12-gallon capacity).
Keep the cream at 58°F to 59°F until it tastes slightly acidic.
Churn and wash
Churn the cream for about 1 hour until buttermilk is drawn off.
Add cold water to the churn and give a few turns, then draw off the water.
Repeat until the water is nearly free from milkiness.
Salt and store
Work the butter with a damp cloth to absorb moisture and buttermilk.
Salt the butter with 1 ounce of salt for every 3 pounds and mix thoroughly.
Weigh the butter and shape it into pound prints.
Place the prints in large tin trays and set in water to harden overnight.
Wrap the butter in damp cloths and store in tin-lined cedar tubs with ice.

What each ingredient does
- Milk
- Its cream separates and ripens, becoming slightly acidic, which gives the butter its flavor.
- Cream (in the method)
- Its fat clumps together during churning to form the butter.
- Coarse sea salt
- Seasons the butter and helps preserve it after the moisture is worked out.
The step that matters
Churn the cream for about 1 hour until buttermilk is drawn off. Churning must continue until the fat clumps and the buttermilk separates. Leftover buttermilk left in the butter can turn it sour and shorten its keeping quality, so the washing and working steps matter.
