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 ↓
Frozen Custard
Ingredients
Directions
Make the custard
Heat the milk in a saucepan until nearly boiling.
In a bowl, beat the egg yolks with the sugar, then gradually add the hot milk.
Whip the egg whites until frothy and fold them into the mixture.
Return the mixture to the saucepan and stir until it thickens into a custard.
Let the custard cool completely, then whisk in the cream.
Freeze and add fruit
Freeze the custard, stirring in the fruit after the second beating.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they set with heat, and whipped whites add lightness.
- Milk
- Forms the liquid base that the eggs thicken into a custard.
- Cream
- Adds fat for a rich, smooth texture that resists iciness.
- Sugar
- Adds sweetness and keeps the frozen custard softer and easier to scoop.
- Berries or peaches
- Add fruity flavor and color to the frozen custard.
The step that matters
Thickening the custard. Egg yolks scramble and turn grainy if overheated, while an underheated custard stays thin. Stir steadily over gentle heat until it coats a spoon.
Swap the peach
How well each one fits the dish's main ingredients (milk, cream, egg, sugar):
- Vanillafits better
- Strawberryfits better
- Raspberryfits about as well
- Peachthe original
Fit is the average pairing score against milk, cream, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
