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 ↓
Cream Custard
Ingredients
Directions
Make the custard
Boil the milk and cream together.
While boiling, add the sugar and cornstarch dissolved in a little cold milk.
Beat the egg whites to a stiff froth.
Add the beaten egg whites just before removing from heat, stirring lightly.
Boil for five minutes after adding the cornstarch.
Serve
Pour into cups with a few drops of different flavoring in each, or mold it.
Serve cold with cream.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Cream
- Adds richness and a smooth, velvety texture to the custard.
- Milk
- Forms the liquid base that the cornstarch thickens into a custard.
- Sugar
- Sweetens the custard and balances the flavor.
- Cornstarch
- Thickens the boiling liquid into a set custard.
- Egg whites
- Whipped to a stiff froth, they lighten the custard's texture.
The step that matters
Add the beaten egg whites just before removing from heat. Stirring lightly keeps the whipped foam from collapsing, so the custard stays light. Removing the pot from heat first limits overcooking of the delicate foam.
Swap the lemon

Fit is the average pairing score against cream, milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
