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

What each ingredient does

Rhubarb
Provides the tart flavor and fibrous pieces that soften and give the jam its body.
Sugar
Draws juice out of the rhubarb overnight, forms the syrup, and adds sweetness and preservation.

The step that matters

Boil the rhubarb gently. A gentle boil lets the syrup concentrate while the rhubarb pieces stay mostly intact. Boiling too hard breaks the fruit down into mush and can scorch the sugar, which darkens and changes the flavor.

Swap the rhubarb

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

  1. Cinnamonfits better
  2. Gingerfits about as well
  3. Rhubarbthe original
  4. Nutmegfits less well

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