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 ↓
Curd for Cheesecakes
Ingredients
Directions
Make the curd
Heat the milk in a clean pan by the fire until it is blood warm.
Add the rennet; too much will make the curd hard and the whey salty.
Wait for the milk to separate into curd and whey, then cut the curd into small pieces.
Alternatively, add a small piece of alum (the size of a nutmeg) and let the milk boil.
Strain the curd from the whey using a fine sieve, then let it drain or press it dry.
Pass the curd through the sieve into a basin.
Finish and fill
Melt the butter and mix it with the curd, then add the eggs.
Add sugar, grated nutmeg, and currants if desired, and mix well.
Fill the cases with the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the curd when set with rennet, and provides the body of the filling.
- Rennet
- Causes the milk to separate into curds and whey, setting the base of the filling.
- Butter
- Adds richness and a soft, smooth texture to the curd.
- Eggs
- Bind the mixture and add structure and richness as they set.
The step that matters
Adding the rennet. Too much rennet makes the curd hard and the whey salty, as the milk sets too firmly and the flavour turns harsh. Measure it carefully and wait for the milk to separate.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (milk, butter, egg, sugar, nutmeg):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against milk, butter, egg, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
