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

What each ingredient does

Fresh cream
Provides fat and richness, giving the set custard a smooth, creamy texture.
Clarified isinglass
Gelatin-like setting agent that firms the cream into a sliceable custard when chilled.
Sweet almonds
Supply the main almond flavour and body once pounded into the base.
Bitter almonds
Add a concentrated, aromatic almond note in small quantity.

The step that matters

Constantly stir the mixture until it boils. Stirring keeps the cream and almond mixture from scorching or curdling on the pan base. Boiling is needed so the isinglass is fully dissolved and mixed in, which lets it set properly when chilled.

Flavor stand-ins for the orange

  1. Vanillabetter flavor fit
  2. Coconutbetter flavor fit
  3. Avocadobetter flavor fit
  4. Orangethe original

Fit is the average pairing score against almond, cream. 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).
