Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Fresh Butter
Ingredients
Directions
Prepare the cream
Ensure the cream temperature is between 55°F to 60°F (13°C to 16°C) before churning.
Churn and wash
Churn the cream with an even stroke for about fifteen minutes until butter forms.
Wash the butter thoroughly to remove buttermilk using a wooden kneading trough.
Salt and finish
Add ¾ ounce to 1 ounce of finely powdered salt for every 3 pounds of butter.
For indifferent butter, wash it with water and bi‑carbonate of soda, then knead with sweet milk, salt, and a little white sugar.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Cream
- Its fat globules churn together to form the butter itself.
- Coarse sea salt
- Adds flavour and helps preserve the finished butter.
- Bi-carbonate of soda
- Neutralises acidity in poorly churned butter, softening its sour off-taste.
- Sweet milk
- Used in kneading to work in moisture and mild dairy flavour.
- White sugar
- Adds a little sweetness to balance the butter's flavour.
The step that matters
Keep the cream within the stated temperature range before churning. Cream that is too cold churns slowly and may not form butter, while cream that is too warm produces soft, greasy butter that is hard to work. The fat must be soft enough to clump but firm enough to separate from the buttermilk.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
