Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides dark color, moisture, and the characteristic gingerbread sweetness and flavor.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Butter
- Adds fat for tenderness and a rich mouthfeel.
- Sour milk
- Its acidity reacts with baking soda to help the cake rise and soften its crumb.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that leavens the batter.
- Flour
- Forms the gluten and starch structure that sets the batter into a cake.
The step that matters
Adding the flour. Flour is added gradually until the batter reaches pound cake consistency. Too much flour makes the cake dense and dry, while too little leaves it loose and unable to hold its rise.
Swap the ginger

Fit is the average pairing score against molasses, egg, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
