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

Pears
Form the body of the preserve, softening as they cook and turning clear in the syrup.
Sugar
Sweetens the fruit and, in a thick syrup, draws out moisture to help preserve it.
Ginger root or cloves
Adds warm, spicy aroma that flavors the pears.

The step that matters

Cook gently and skim the foam. Gentle heat keeps the pears from breaking apart or scorching while sugar slowly penetrates the fruit. Skimming removes foam, which keeps the syrup clear and the fruit looking translucent.

Swap the pear

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

  1. Lemonfits better
  2. Orangefits about as well
  3. Limefits about as well
  4. Pearthe original

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