Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Gelatine
Sets the syrup into a firm, sliceable jelly once cooled.
Granulated sugar
Provides sweetness and body, and helps give the jelly its chewy texture.
Walnut meats
Add crunch and nutty flavour against the soft jelly.
Orange juice and rind
Add citrus aroma and flavour to the jelly.

The step that matters

Boil for about 10 minutes. The mixture must be boiled long enough to concentrate the sugar and reach the right consistency. Too little boiling leaves the jelly too soft to set firmly, while overboiling makes it stiff and hard.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, orange, lemon, meat):

  1. Almondfits better
  2. Pistachiofits about as well
  3. Chickpeafits about as well
  4. Walnutthe original

Fit is the average pairing score against sugar, orange, lemon, meat. Candidates are from the same food group and used in at least 100 recipes.
