Why it works: Vanilla and peach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 558 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Chocolate Ice Cream
Ingredients
Directions
Make the custard
Rub the grated chocolate into the milk until smooth.
Add the beaten eggs and sugar, then beat well.
Cook the mixture in a double boiler until thickened.

Flavor with vanilla.
Freeze
Put the mixture in a freezer.
When it begins to set, add the rich cream.
If desired, add the preserved peaches when the cream is almost frozen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard when cooked and help give the ice cream a smooth, rich body.
- Rich cream
- Adds fat and richness, giving a smoother texture and softer bite to the frozen ice cream.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer when frozen.
- Milk
- Forms the liquid base that the chocolate, eggs and sugar are combined into.
The step that matters
Cook the mixture in a double boiler until thickened. Gentle heat lets the egg proteins thicken the base slowly. Overheating can curdle the eggs and leave a grainy texture in the finished ice cream.
Swap the peach
The recipe marks peach as optional. How well each one fits the dish's main ingredients (chocolate, milk, egg, sugar, vanilla, cream):
- Coconutfits better
- Strawberryfits better
- Raspberryfits better
- Peachthe original
Fit is the average pairing score against chocolate, milk, egg, sugar, vanilla, cream. Candidates are from the same food group and used in at least 100 recipes.
