Ginger and sugar barely smell alike, yet cooks put them together in 14,054 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

Vegetable marrow
Forms the bulk of the preserve; it softens and becomes translucent as it absorbs the sugar syrup.
Sugar
Sweetens and preserves the marrow, and thickens the syrup as it is boiled down.
Lemons
Add acidity and a bright flavour that balances the sweetness of the syrup.
Ginger
Adds a warm, aromatic spice flavour to the syrup.

The step that matters

Boiling the syrup several times until strong and transparent. Sugar must reach a high enough concentration to preserve the marrow and make it clear. Under-boiled syrup stays thin and may let the preserve spoil, while repeated boiling concentrates the sugar and gradually clarifies the syrup.

Swap the lemon

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

  1. Lemonthe original
  2. Orangefits about as well
  3. Limefits less well
  4. Vanillafits less well

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