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, sliceable body as it cools.
Orange juice
Provides the main flavour and acidity that brightens the set mixture.
Lemon juice
Adds sharp acidity that balances the sweetness and sharpens the citrus flavour.

The step that matters

Dissolve the isinglass fully in the milk. Isinglass is a gelling agent. If it is not completely dissolved before the juice is added, it cannot set evenly, and the finished cake may be lumpy or soft in places.

Swap the orange

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

  1. Vanillafits better
  2. Orangethe original
  3. Figfits less well
  4. Blueberryfits less well

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