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

What each ingredient does

Cornmeal
Gives the bread its coarse, crumbly body and characteristic grainy texture.
Rye flour
Adds flavor and a denser crumb compared with wheat flour alone.
Wheat flour
Provides the gluten-based structure that holds the loaf together.
Molasses
Adds sweetness, dark color, and a deep, caramel-like flavor.
Egg
Binds the batter and adds structure as it sets.
Baking soda
Reacts with the molasses's acidity to lift the batter and lighten the crumb.

The step that matters

Keeping the pudding boiler at a steady boil. The bread cooks by steam over three hours, so the water must stay topped up and simmering. If it boils dry, the bread scorches or cooks unevenly and turns out dense.

Swap the raisin

How well each one fits the dish's main ingredients (milk, wheat, flour, butter, molasses, egg, rye):

  1. Raisinthe original
  2. Vanillafits about as well
  3. Figfits about as well
  4. Blueberryfits less well

Fit is the average pairing score against milk, wheat, flour, butter, molasses, egg, rye. Candidates are from the same food group and used in at least 100 recipes.
