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

What each ingredient does

Rhubarb
Provides the main tart flavour and colour once its juice is strained out.
Sugar
Balances the tartness and adds sweetness to the liquid.
Lemon rind
Adds aromatic citrus oils to the cooking liquid.

The step that matters

Stir in the sugar until dissolved. Sugar that is not fully dissolved leaves grains in the chilled liquid, making it gritty. Stirring until clear ensures the sugar is evenly distributed and fully sweetens the sherbet.

Swap the rhubarb

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

  1. Cinnamonfits better
  2. Gingerfits better
  3. Marjoramfits better
  4. Rhubarbthe original

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