Why it works: Sugar and cream 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
Prepare
Sweeten the milk with white sugar to taste.
Stir in 1 tablespoon of wine that has had rennet soaked in it.
Add more wine if needed for flavor.
Soak the rennet in water instead of using wine, if preferred.
Prepare the custard one hour before serving in warm weather to ensure the curd is soft.
Stir the mixture after the rennet is added.
Set and serve
Pour the mixture into cups to coagulate or serve in a glass bowl.
Serve with cream.
Optionally sprinkle with grated nutmeg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the custard as the rennet sets it into a soft curd.
- Rennet
- Enzyme that coagulates the milk proteins, setting the custard into a soft curd.
- White sugar
- Adds sweetness to the milk before it sets.
The step that matters
Stir the mixture after the rennet is added. Rennet must be evenly distributed through the milk so the whole batch sets uniformly. Stirring too little leaves unset or uneven patches, while the curd should be left undisturbed once it begins to set.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (milk, sugar, wine, cream):
- Cinnamonfits better
- Nutmegthe original
- Peppermintfits less well
- Gingerfits less well
Fit is the average pairing score against milk, sugar, wine, cream. Candidates are from the same food group and used in at least 100 recipes.
