Make the jelly

  1. Dissolve the isinglass in the quince juice over a clear fire for 20 to 30 minutes until it jellies when falling from a spoon.

  2. Remove any scum that forms on top.

Combine and set

  1. Gradually pour the boiling jelly into the thick cream.

  2. Stir briskly until nearly cold.

  3. Pour the mixture into a mould rubbed with a small amount of pure salad oil or dipped in cold water.

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

What each ingredient does

Isinglass
Sets the liquid into a firm, tender jelly as it cools.
Quince juice
Provides the main flavour and liquid base of the dessert.
Thick cream
Adds richness and a smooth, creamy texture to the set jelly.
Sugar
Adds sweetness and balances the tartness of the quince juice.

The step that matters

Stir the jelly into the cream while it is still boiling and stir until nearly cold. Isinglass must be fully dissolved and then cooled gradually; pouring it into cream too cold can cause lumps or uneven setting, while stirring keeps the mixture smooth as it thickens.

Swap the quince

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Raspberryfits better
  4. Quincethe original

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