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 Fruit Custard
Ingredients
Directions
Make the custard
Beat the egg yolks and sugar together until well combined.
Heat the milk almost to boiling, then gradually add it to the egg mixture, stirring constantly.
Return the mixture to the heat and stir until it slightly thickens, being careful not to curdle.
Freeze and finish
When the custard is partly frozen, stir in the whipped cream and mix for a few more minutes.
Gently fold in the fruit.
Transfer the mixture to a mold and place it in a fresh supply of ice and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set gently with heat.
- Milk
- Provides the liquid base that the yolks thicken into a smooth custard.
- Whipped cream
- Adds air and fat, giving the frozen dessert a light, creamy texture.
- Sugar
- Sweetens the custard and lowers the freezing point, keeping it softer when frozen.
- Peaches or berries
- Add fruit flavor, aroma and moisture to the frozen custard.
The step that matters
Returning the mixture to the heat. Egg yolks thicken as they warm but curdle if overheated. Stir steadily and stop as soon as the custard slightly thickens, so it stays smooth.
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.
