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

What each ingredient does

Dried prunes
Provide the main body, sweetness and deep flavor of the marmalade.
Dried peaches
Add mellow fruity sweetness and help give the puree a smooth, soft texture.
Dried apples
Contribute pectin and body that help the puree thicken as it cooks.
Sugar
Adds sweetness and, as it dissolves and concentrates, helps the mixture set.
Lemon juice
Adds acidity that brightens the flavor and supports thickening.

The step that matters

Cook until thickened. Simmering drives off water and concentrates the fruit and sugar, so the mixture thickens as it cools. Stopping too early leaves it runny, while overcooking can make it stiff and sticky.

Swap the lemon

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

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

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