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

What each ingredient does

Rhubarb
Provides the bulk of the jam and its tart, fresh flavour.
Loaf sugar
Sweetens the jam and helps it set as it cooks and thickens.
Whole ginger
Adds a warm, spicy aroma that complements the tart rhubarb.

The step that matters

Boil until the mixture is clear. Boiling must go on long enough for the sugar to dissolve fully and the jam to reach a set, since undercooked jam stays runny and spoils more readily in storage.

Swap the rhubarb

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

  1. Cinnamonfits better
  2. Turmericfits better
  3. Clovefits better
  4. Rhubarbthe original

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