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

What each ingredient does

Scarlet strawberries
Provide the main flavour and colour of the jelly.
Currant jelly
Adds extra fruit flavour and body to the mixture.
Lemon juice
Adds acidity that brightens the sweetness and flavour.
Isinglass
Gelatin-like setting agent that firms the liquid into a jelly.

The step that matters

Adding the isinglass. Isinglass must be added while the mixture is cool but still liquid. If it is too hot, the gelling agent can lose strength, and if the mixture has already begun to congeal, it will not blend evenly and the jelly may set unevenly.

Swap the currant

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

  1. Orangefits better
  2. Vanillafits better
  3. Limefits better
  4. Currantthe original

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