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

What each ingredient does

Hard green pears
Provide the fruit itself, softening into tender pieces while holding their shape during stewing.
Molasses
Adds sweetness, dark color and a deep, treacle-like flavor to the syrup.
Ginger
Adds warm, spicy aroma that balances the sweetness of the molasses.

The step that matters

Boiling the molasses syrup. Molasses is thick and sugary, so it can scorch on the bottom of the pan during the 30-minute boil. Keep the heat steady and stir or skim so it does not burn, which would leave a bitter taste.

Swap the pear

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

  1. Orangefits better
  2. Raisinfits better
  3. Limefits about as well
  4. Pearthe original

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