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

What each ingredient does

Molasses
Adds sweetness, dark color and moisture to the pudding.
Baking soda
Reacts with the acidic molasses to produce gas that lightens the batter.
Suet
Adds fat that keeps the pudding moist and rich as it steams.
All-purpose flour
Provides the structure that holds the pudding together as it sets.
Sweet milk
Adds moisture and helps the flour hydrate into a smooth batter.

The step that matters

Transfer the mixture to a greased pudding mold.. Greasing keeps the pudding from sticking when unmolded. The mold should be filled without overfilling, since the batter rises and needs room to expand during steaming.
