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 ↓
Walnut Cream Ice
Ingredients
Directions
Make the walnut base
Pound the walnut kernels in a mortar with enough milk to create a smooth paste.
Mix the walnut puree with the heavy cream and sugar until smooth.
Finish and freeze
Fold in the whipped cream gently.
Freeze the mixture in an ice cream maker according to the manufacturer's instructions.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnut kernels
- Provide the main flavor and body, becoming a smooth paste that gives the ice cream its nutty character.
- Heavy cream
- Adds fat and richness, giving the frozen ice cream a smooth, creamy texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer and scoopable.
- Whipped cream
- Adds air and lightness, making the texture fluffier and less dense.
The step that matters
Fold in the whipped cream gently. Folding keeps the air trapped in the whipped cream. Vigorous stirring deflates it, leaving a denser, heavier ice cream.
Swap the walnut
How well each one fits the dish's main ingredients (milk, cream, sugar):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Walnutthe original
Fit is the average pairing score against milk, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
