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 ↓
Spanish-Nut Ice Cream
Ingredients
Directions
Prepare the nuts
Preheat the oven and roast the nuts.
Pound the roasted nuts with a little cream.
Make the custard
In a saucepan, combine the nut mixture, 1 pint of cream, 8 egg yolks, and 6 ounces of pounded sugar.
Heat the mixture gently, stirring constantly until it thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Nuts
- Provide the main flavour and body of the ice cream base.
- Cream
- Adds richness and fat, giving the ice cream a smooth, creamy texture.
- Egg yolks
- Thicken the custard as they heat and add richness and emulsifying power.
- Sugar
- Adds sweetness and softens the texture of the frozen dessert.
The step that matters
Heating the custard gently. Egg yolks thicken through gentle heat; if the mixture gets too hot it can scramble, curdling the custard. Constant stirring spreads heat evenly and prevents this.
Swap the nuts
How well each one fits the dish's main ingredients (cream, egg, sugar):
- Almondfits better
- Pistachiofits better
- Chestnutfits about as well
- Nutsthe original
Fit is the average pairing score against cream, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
