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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide the main flavor and a rich, slightly oily body to the ice.
- Egg yolks
- Thicken the custard as it cooks and give the ice a smooth, creamy texture.
- Cream
- Adds fat and richness, keeping the frozen texture smooth and soft.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice from freezing too hard.
- Milk
- Helps grind the walnuts into a smooth paste and adds moisture.
The step that matters
Cook the mixture over low heat to form a custard. Egg yolks thicken when heated gently, but too much heat can scramble them into lumps. Low, steady heat and stirring keep the custard smooth before it is strained and frozen.
Swap the walnut
How well each one fits the dish's main ingredients (milk, cream, sugar, brandy, egg):
- Almondfits better
- Walnutthe original
- Chestnutfits about as well
- Cocoafits about as well
Fit is the average pairing score against milk, cream, sugar, brandy, egg. Candidates are from the same food group and used in at least 100 recipes.
