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

What each ingredient does

Seville oranges
Provide the bitter, acidic flavour and the pectin that helps the paste set.
Sugar
Sweetens the bitter oranges and, with the fruit, thickens the paste into a set filling.
Butter
Adds richness and a smoother, glossier texture to the orange paste.
Puff pastry
Forms the crisp, flaky shell that holds the orange paste.

The step that matters

Beat the oranges and sugar into a paste. The paste must be beaten until smooth and thick enough to hold its shape. Too little cooking or beating leaves the filling runny, while the sugar and the fruit's pectin together are what allow it to set firmly when cooled.

Swap the orange

How well each one fits the dish's main ingredients (sugar, walnut, butter):

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Orangethe original

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