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
Prepare the pistachio paste
Blanch the pistachio nuts, then pound them into a fine paste, adding a little rose water to help.
Make the base
Heat the cream and sift in the sugar, stirring until dissolved.
Allow the mixture to cool, then add the pistachio paste.
Color the mixture a pale green using spinach coloring if desired.
Optionally, flavor with vanilla.
Freeze
Freeze according to your ice cream maker's instructions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Provides fat and richness, giving the ice cream a smooth, creamy body.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer and scoopable.
- Egg yolks
- Act as emulsifiers and thickeners, adding richness and a smooth texture.
- Pistachio nuts
- Supply the main nutty flavour and color to the ice cream.
Swap the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (cream, sugar, egg, pistachio, nuts, rose, vanilla):
- Arrowrootfits better
- Sweet potatofits about as well
- Spinachthe original
- Beetrootfits about as well
Fit is the average pairing score against cream, sugar, egg, pistachio, nuts, rose, vanilla. Candidates are from the same food group and used in at least 100 recipes.
