Why it works: Sugar and cream 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 ↓
Coffee Ice Cream
Ingredients
Directions
Make the custard
Scald the milk with the coffee.
Gradually add the hot milk to the slightly beaten egg yolks mixed with sugar and salt.
Cook over hot water until the mixture thickens.
Add 1 cup of cream and let it stand on the back of the stove for 20 minutes.
Cool and freeze
Cool the mixture, then add the remaining cream and brandy.
Strain through double thickness of cheesecloth and freeze until very stiff.
Shape and serve
Shape into individual pyramids using a scoop and roll in the chopped walnut meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground coffee
- Supplies the main coffee flavor, infused into the hot milk.
- Egg yolks
- Thicken the custard as they cook and add richness to the ice cream.
- Cream
- Adds fat that makes the ice cream rich and smooth.
- Sugar
- Sweetens the base and softens the texture of the frozen ice cream.
- Brandy
- Adds aroma and helps keep the frozen ice cream scoopable.
The step that matters
Cook over hot water until the mixture thickens. Egg yolks thicken custard as they gently heat, but high heat makes them scramble and curdle. Cooking over hot water keeps the temperature gentle, so stir steadily and watch for a smooth, coating consistency.
Swap the walnut
How well each one fits the dish's main ingredients (coffee, sugar, milk, cream, egg, brandy, meat):
- Cocoafits about as well
- Walnutthe original
- Almondfits about as well
- Pecansfits about as well
Fit is the average pairing score against coffee, sugar, milk, cream, egg, brandy, meat. Candidates are from the same food group and used in at least 100 recipes.
