Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and add richness and tenderness.
- Sugar
- Sweetens the pudding and helps the creamed mixture hold air.
- Eggs
- Bind the batter and add structure as the pudding sets.
- Flour
- Provides the main structure that sets as the pudding steams.
- Sour milk
- Adds acidity and moisture, and reacts with the baking soda to lighten the batter.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the pudding rise.
The step that matters
Add the dissolved baking soda to the mixture. Baking soda starts releasing gas as soon as it meets the acidic sour milk and liquid. Adding it promptly and mixing gently keeps the bubbles in the batter so the pudding rises well when steamed.
Swap the nutmeg
How well each one fits the dish's main ingredients (molasses, butter, sugar, flour, milk, egg):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against molasses, butter, sugar, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
