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 texture.
- Sugar
- Sweetens the mixture and lowers its freezing point, keeping the ice cream softer.
- Egg
- Adds richness and helps emulsify the mixture for a smooth, stable texture.
- Walnut meats
- Add crunch and a nutty flavour that contrasts with the creamy base.
The step that matters
Freeze until it starts to set before adding the walnuts. If the mixture is fully frozen first, the walnuts will not distribute evenly. Stirring while partly set keeps them suspended, and the walnuts should be well drained of soaking liquid so they do not make the ice cream icy.
Swap the walnut
How well each one fits the dish's main ingredients (meat, cream, sugar, egg):
- Almondfits about as well
- Pecansfits about as well
- Walnutthe original
- Filbertfits about as well
Fit is the average pairing score against meat, cream, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
