Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the sponge together as the batter sets.
- Baking soda
- Reacts with the sour milk to release gas, lifting the batter so it rises.
- Sour milk
- Its acidity activates the baking soda and adds moisture to the batter.
- Molasses
- Adds sweetness, dark color, and moisture, and contributes to the gingerbread flavor.
- Butter
- Adds fat for a tender crumb and richer flavor.
The step that matters
Dissolve the baking soda in the sour milk, then add it promptly. Baking soda reacts with the acid in sour milk to release carbon dioxide bubbles. If the mixture sits too long before baking, or the flour is added slowly, some of that gas escapes and the sponge rises less.
