Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, wobbly gel as it cools.
- Sugar
- Adds sweetness and balances the sharpness of the lemon.
- Lemon juice
- Adds acidity that brightens the flavour of the jelly.
- Walnuts
- Add crunch and a contrasting texture to the soft jelly.
The step that matters
Let the mixture cool until partially set before folding in the fruit. Gelatine sets as it cools. If the mixture is still very liquid, the chopped walnuts, orange and banana will sink or settle unevenly instead of staying suspended through the jelly.
Swap the walnut
How well each one fits the dish's main ingredients (lemon, sugar, orange, banana):
- Almondfits better
- Pistachiofits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against lemon, sugar, orange, banana. Candidates are from the same food group and used in at least 100 recipes.
