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
Prepare the pistachios
Scald, clean, and pound the pistachios to a pulp.
Make the custard
In a saucepan, combine the pistachio pulp, crushed sugar, egg yolks, salt, and milk or cream.
Heat the mixture, stirring until it thickens.
Strain the mixture through a fine sieve into a basin.
Mix in the orange flower water and spinach-green, ensuring the coloring is well incorporated.
Freeze
Pour the mixture into an ice cream maker and freeze until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pistachios
- Provide the main flavor and the pale green color of the ice cream.
- Egg yolks
- Thicken the custard and add richness and a smooth, creamy texture.
- Milk or cream
- Supply the liquid base and fat that give the ice cream its body.
- Crushed loaf sugar
- Sweetens the base and helps keep the frozen texture soft.
The step that matters
Heating the custard until it thickens. Egg yolks thicken as they heat, but if the mixture gets too hot it can curdle and turn grainy. Stirring constantly and stopping once it coats a spoon keeps the custard smooth.
Swap the orange
How well each one fits the dish's main ingredients (pistachio, sugar, egg, milk, spinach):
- Vanillafits better
- Lemonfits better
- Coconutfits better
- Orangethe original
Fit is the average pairing score against pistachio, sugar, egg, milk, spinach. Candidates are from the same food group and used in at least 100 recipes.
