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 Made with Rennet
Ingredients
Directions
Prepare
Warm the milk to the temperature of fresh milk.
Sweeten the milk to taste and add nutmeg for flavor.
Soak the rennet in warm water for a few moments.
Set and serve
Place the rennet in the middle of the milk pan with a string attached for easy removal.
Set the pan in a cool place until the custard solidifies.
Serve with cream.

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 rennet coagulates its proteins into a soft set.
- Rennet
- Enzyme that causes the warm milk to coagulate into a tender, spoonable curd.
The step that matters
Setting the pan in a cool place. Rennet sets milk best while it stays still and undisturbed. Moving or jarring the pan during setting can break the forming curd and leave the custard grainy or watery.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, sugar, cream):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Peppermintfits less well
Fit is the average pairing score against milk, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
“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.
