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

What each ingredient does

Rhubarb
Provides the tart flavour and the bulk of the marmalade.
Sugar
Sweetens the fruit and helps the mixture thicken and preserve when boiled.
Oranges
Adds citrus aroma and acidity from the rind and juice.

The step that matters

Boil the mixture for 20 minutes. Boiling dissolves the sugar and concentrates the mixture so it sets as a preserve. Boiling too briefly can leave it runny and more prone to spoiling in the jar.

Swap the orange

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

  1. Vanillafits better
  2. Figfits about as well
  3. Quincefits about as well
  4. Orangethe original

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