Why it works: Milk and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Cold Custard
Ingredients
Directions
Sweeten the milk with white sugar to your taste.
Stir in 1 tablespoon of wine that has had rennet soaked in it.
If the flavor is not strong enough, add more wine without rennet.

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
- Milk
- Forms the base that rennet coagulates into a soft, set custard.
- Rennet
- Enzyme that causes milk proteins to coagulate and set into a curd.
- White sugar
- Adds sweetness to balance the milk.
- Wine
- Carries the soaked rennet and adds flavor to the custard.
The step that matters
Stir in the rennet wine evenly. Rennet is an enzyme that causes milk proteins to coagulate into a set curd. Mixing it thoroughly distributes it so the whole custard sets evenly rather than in patches.
