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 ↓
Cold Custard
Ingredients
Directions
Make the custard
Mix the milk, cream, and sugar in a bowl.
Soak the rennet in the white wine, then stir it into the milk mixture.
Pour the mixture into custard cups.
Place the cups in a warm area until they form a firm curd.
Chill and serve
Chill the cups in the refrigerator and grate nutmeg over them before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole milk
- Provides the main liquid and body for the custard to set into.
- Heavy cream
- Adds fat, richness and a smoother, softer texture to the set custard.
- Powdered white sugar
- Sweetens the custard and dissolves easily into the cold milk mixture.
- Washed rennet
- Enzyme that causes the milk to coagulate into a firm curd.
The step that matters
Place the cups in a warm area until they form a firm curd. Rennet only sets milk within a suitable temperature range, so the curd may stay loose if the area is too cold or the enzyme is not evenly mixed in first.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, cream, sugar, white wine):
- Cinnamonfits about as well
- Nutmegthe original
- Peppermintfits less well
- Gingerfits less well
Fit is the average pairing score against milk, cream, sugar, white wine. Candidates are from the same food group and used in at least 100 recipes.
