Rhubarb Ginger

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

  1. In a pot, combine rhubarb, sugar, lemon juice, lemon rind, and ginger root.

  2. Cover and cook over medium heat until thickened, about 20-30 minutes.

  3. Stir occasionally to prevent sticking.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Rhubarb
Provides the main bulk and tart flavor, and softens into a thick sauce as it cooks.
Sugar
Sweetens the rhubarb and helps it set into a thick, glossy texture.
Lemon juice
Adds acidity that brightens the rhubarb and balances the sugar.
Lemon rind
Adds citrus aroma from its oils.
Ginger root
Adds a warm, spicy aroma and a bit of heat.

The step that matters

Stirring while it thickens. Rhubarb and sugar can scorch on the bottom of the pot before the mixture thickens. Cooking over medium heat and stirring occasionally spreads the heat and keeps the sugar from burning.

Swap the rhubarb

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

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

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