  3. Stir in the Constantia wine and strain through a muslin cloth folded three or four times.

Mould and set

  1. Soak the moulds in water for 2 to 3 hours before use.

  2. Mould the jelly when cool, keeping back any sediment.

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

What each ingredient does

Isinglass
Fish-based gelatin that sets the liquid into a firm, clear jelly when cooled.
Good loaf sugar
Adds sweetness and balances the acidity of the wine and orange.
Seville orange rind
Adds bitter aromatic oils that flavour the syrup as it simmers.
Constantia wine
Provides the main flavour and liquid of the jelly.

The step that matters

Straining through muslin. Folding the muslin three or four times lets the liquid run clear by catching fine particles. Leftover sediment clouds the jelly and can spoil its appearance, so it is kept back when moulding.

Swap the orange

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

  1. Vanillafits better
  2. Applefits better
  3. Grapefits better
  4. Orangethe original

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