Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda, producing gas that lightens the batter.
- Molasses
- Adds sweetness, dark colour, and moisture, and its acidity also helps the baking soda react.
- Butter
- Adds fat for richness and a tender texture.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas for rising.
- Flour
- Provides the structure that holds the pudding together as it sets.
The step that matters
Pour the batter into the pot promptly. Baking soda starts reacting with the acidic sour milk and molasses as soon as it is mixed in. Delaying the pour lets some of the gas escape before the pudding sets, so it may turn out denser.
