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

What each ingredient does

Flour
Provides the starch and gluten structure that holds the pudding together as it cooks.
Baking soda
Reacts with the acid in the sour milk to release gas, helping the pudding rise and lighten.
Sour milk
Adds moisture and acidity, which activates the baking soda and tenderizes the crumb.
Suet
Adds fat that keeps the pudding moist and rich as it steams.
New orleans molasses
Adds sweetness, moisture and a dark, deep flavor.
Raisins
Add chewy texture and concentrated sweetness throughout the pudding.

The step that matters

Boil for three hours. Long, steady boiling cooks the dense batter evenly through to the center. Heat slowly sets the starches and proteins, so a pudding cooked too briefly or at too low a heat stays wet and doughy inside.
