Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Boiled Custard, or Mock Cream
Ingredients
Directions
Make the custard
Heat the milk in a saucepan until nearly boiling.
Dissolve the corn starch in a little cold milk and add it to the hot milk.
Beat the eggs and mix in the powdered sugar, then add to the saucepan.
Stir briskly and let it boil once or twice until thickened.
Finish and serve
Flavor to your taste and serve very cold as a substitute for ice cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the custard as it heats and gelatinizes, giving it body.
- Eggs
- Add richness and help set the custard as the proteins coagulate with heat.
- Milk
- Forms the liquid base that the starch and eggs thicken.
- Powdered sugar
- Adds sweetness and dissolves easily into the warm custard.
The step that matters
Stir briskly while the custard comes to a boil. Constant stirring keeps the starch and egg proteins dispersed evenly so they thicken smoothly without lumps or scorching on the bottom of the pan.
Swap the lemon

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