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 separated.
Add cold water to the churn and give a few turns.
Draw off the water.
Repeat until the water is nearly free from milkiness.
Salt and set
Work the butter with a damp cloth to absorb moisture and buttermilk.
Salt the butter with 1 ounce of salt per 8 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 out and is churned into butter fat.
- Cream (in the method)
- Its fat churns into the solid butter, giving richness and texture.
- Salt
- Adds flavour and helps preserve the finished butter.
The step that matters
Churn the cream for about 1 hour until buttermilk is separated. Churning too short leaves fat globules unclumped, while overchurning can make the butter grainy. Stop when the butter has clumped and the buttermilk is clearly separated, so the butter holds together and keeps well.
