The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

  1. Wine + lemontop 13% of all pairs

    Shared aroma: decanal (soap, orange peel).

  2. Lemon + sugartop 18% of all pairs

    Shared aroma: 2-nonenal (fatty, green).

  3. Wine + sugartop 31% of all pairs

    Shared aroma: beta-damascenone (apple, rose).

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Iceland moss
Its gel-forming starch thickens the liquid into a soft, jelly-like set.
Wine
Adds aromatic flavor and a mild acidity to the finished jelly.
Lemon juice
Adds acidity that brightens the flavor and balances sweetness.
Sugar
Adds sweetness to balance the tartness of the lemon and wine.

The step that matters

Boil the mixture until reduced to 1 pint. Reducing by boiling concentrates the soluble starch from the moss, so the liquid has enough body to set as a jelly once cooled. Too little reduction leaves it runny.

Swap the lemon

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

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

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