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.

    Shared aroma: decanal (soap, orange peel).

  2. Sugar + lemontop 18% of all pairs

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

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

Sugar and lemon 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

Hartshorn shavings
Gelatin-rich shavings that set the liquid into a jelly as it cools.
Sugar
Adds sweetness that balances the tartness of the lemon juice.
Lemon juice
Adds acidity that brightens the flavour and sharpens the sweetness.
Wine
Adds flavour and aroma to the finished jelly.

The step that matters

Boil until reduced to ½ quart. Boiling concentrates the dissolved gelatin from the hartshorn, so the liquid has enough setting power to firm up as it cools. Stopping early leaves the jelly too soft to hold its shape.

Swap the lemon

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

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

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