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
- Eggs
- Thicken the custard base as they set gently with warming, giving body to the ice cream.
- Sugar
- Sweetens the base and helps keep the frozen texture softer and smoother.
- Cream
- Provides fat and richness, making the ice cream creamy and smooth on the palate.
- English walnut meats
- Add nutty flavour and a textured crunch throughout the frozen custard.
The step that matters
Warming the cream without boiling. Heat gently until the mixture just begins to thicken. Boiling can curdle the egg proteins, leaving a grainy, lumpy custard instead of a smooth base.
Swap the walnut
How well each one fits the dish's main ingredients (cream, sugar, egg, meat):
- Almondfits about as well
- Pecansfits about as well
- Walnutthe original
- Filbertfits about as well
Fit is the average pairing score against cream, sugar, egg, meat. Candidates are from the same food group and used in at least 100 recipes.
