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

What each ingredient does

Baking soda
Reacts with the molasses acidity to produce gas, helping the pudding rise and lighten.
Cream of tartar
Provides acid that works with the baking soda to leaven the batter.
Molasses
Adds moisture, dark color, and a rich sweetness with a slight acidity.
Butter
Adds fat for tenderness and richness in the crumb.
Flour
Provides the structure that sets the pudding as it cooks.

The step that matters

Pour the mixture into a mold and boil for four hours. The mold must be sealed and the water kept at a steady boil for the full time; a lower or uneven heat leaves the pudding dense and underdone, while the batter needs room to rise.

Swap the raisin

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

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

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