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

What each ingredient does

Quince juice
Forms the flavourful liquid base that the mixture sets from.
Almonds
Contribute richness and a delicate nutty flavour through their cream.
Sugar
Sweetens the quince juice and balances its natural tartness.
Isinglass
Acts as a gelling agent that lets the mixture set firm when cool.

The step that matters

Dissolving the isinglass. Isinglass must be fully dissolved into the hot liquid and simmered before cooling. If it is not evenly distributed, it can set unevenly or leave lumps, so the mixture will not firm up uniformly when moulded.

Flavor stand-ins for the quince

  2. Raisinbetter flavor fit
  3. Figbetter flavor fit
  4. Quincethe original

Fit is the average pairing score against almond, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
