Why it works: Pistachio and spinach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 110 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Pistachio Cream Ice
Ingredients
Directions
Make the custard
Blanch pistachio nuts and pound them in a mortar with lemon rind and sugar until smooth.
Gradually add milk and mix well, then work in egg yolks.
Once cold, strain custard through a fine sieve.
Finish and freeze
Color mixture pale green, fold in whipped cream, and freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pistachio nuts
- Provide the main flavor and the pale green color of the ice cream base.
- Egg yolks
- Thicken the custard and add richness, giving the frozen ice a smooth, creamy texture.
- Whipped cream
- Adds fat and air, making the frozen texture lighter and creamier.
- Sugar
- Sweetens the base and softens the texture of the frozen ice.
- Milk
- Forms the liquid base that the egg yolks thicken into custard.
The step that matters
Work in egg yolks gradually and cool the custard before straining. Adding egg yolks to hot or unevenly mixed liquid can scramble them into lumps. Letting the custard cool before straining removes any small bits and leaves a smooth base for freezing.
Swap the nuts
How well each one fits the dish's main ingredients (pistachio, sugar, lemon, milk, egg, cream, spinach):
- Cashew nutfits better
- Almondfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against pistachio, sugar, lemon, milk, egg, cream, spinach. Candidates are from the same food group and used in at least 100 recipes.
