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

What each ingredient does

Pears
Provide the fruit pulp that becomes the body and flavor of the marmalade.
Sugar
Sweetens the pulp and, as it cooks down, helps it thicken to a stiff set.

The step that matters

Simmering without scorching. Once the sugar is stirred in, the pulp can burn on the bottom of the pan. Scorched sugar turns bitter and dark, spoiling the flavor of the whole batch.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (pear, sugar, apple):

  1. Plumfits better
  2. Apricotfits better
  3. Vanillafits better
  4. Lemonthe original

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