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 Ice Cream
Ingredients
Directions
Make the custard
In a saucepan, combine pistachio nuts, sugar, egg yolks, orange-flower water, and milk or cream.
Heat the mixture over low heat, stirring constantly until it thickens.
Strain the mixture into a bowl.
Color and freeze
In a separate bowl, mix spinach with ½ pint of milk.
Stir the spinach mixture into the pistachio mixture until well combined.
Freeze the mixture like other ice creams.

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 fat-rich body of the ice cream.
- Egg yolks
- Thicken the custard as they heat and add richness and smoothness.
- Sugar
- Sweetens the base and keeps the frozen texture softer.
- Milk or cream
- Supplies the liquid base and fat that give the ice cream its creaminess.
- Spinach
- Adds the green color that gives the ice cream its pistachio-green appearance.
The step that matters
Heating the custard over low heat. Egg yolks thicken gently around 160°F; heating too fast or without constant stirring can scramble them into lumps, so keep the heat low and stir steadily until it coats a spoon.
Swap the orange
How well each one fits the dish's main ingredients (pistachio, nuts, sugar, egg, milk, spinach):
- Vanillafits better
- Coconutfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against pistachio, nuts, sugar, egg, milk, spinach. Candidates are from the same food group and used in at least 100 recipes.
