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

What each ingredient does

Iceland moss
Its natural gums thicken the liquid as it cooks, setting it into a jelly.
Wine
Adds acidity and aroma that balance the sweetness and mild flavor of the jelly.
Lemon juice
Adds brightness and acidity that sharpen the flavor of the jelly.
Sugar
Adds sweetness to balance the tartness of the lemon juice and wine.

The step that matters

Boil the moss until reduced to 1 pint. Moss gums set only when enough liquid has evaporated and the mixture is concentrated. Boiling too briefly leaves a thin liquid, while the reduction must stop at the stated volume for a firm jelly.

Swap the lemon

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

  1. Vanillafits better
  2. Applefits better
  3. Figfits better
  4. Lemonthe original

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