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
In a saucepan, combine the milk or cream, sugar, pistachio pulp, and egg yolks.
Heat the mixture over low heat, stirring until it thickens.
Strain the mixture into a bowl to remove any solids.
Flavour and freeze
Mix in the orange-flower water and spinach greening until smooth.
To ensure even coloring, first mix some of the cream with the greening before combining.
Chill the mixture and then freeze it 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
- Milk or cream
- Forms the liquid base and supplies fat, giving the ice cream its creamy body.
- Sugar
- Adds sweetness and keeps the frozen texture softer by lowering the freezing point.
- Egg yolks
- Thicken the custard as they heat and add richness and emulsifying power.
- Pistachios
- Provide the main nutty flavour and the pale green base colour of the ice cream.
- Orange-flower water
- Adds a floral aroma that complements the pistachio flavour.
The step that matters
Heating the custard over low heat. Egg yolks thicken at gentle heat but scramble if overheated, leaving lumps. Low, steady heat with constant stirring keeps the custard smooth and lets it thicken evenly.
