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

What each ingredient does

Rhubarb
Provides the bulk and tart flavor of the preserve, and breaks down into the fruit body as it cooks.
Sugar
Adds sweetness, draws moisture out of the rhubarb, and thickens into a syrup that helps preserve it.

The step that matters

Cook slowly until the sugar dissolves. Sugar must dissolve gently before the mixture gets hot. If it is heated hard while still grainy, it can scorch on the bottom of the kettle or form crystals, giving a burnt taste and a gritty texture.

Swap the rhubarb

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

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

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