The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Adds moisture and acidity that activates the baking soda for rising.
- Molasses
- Adds sweetness, deep colour, and moisture to the batter.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Flour
- Provides structure that sets the batter as it bakes.
- Ground ginger
- Provides the characteristic warm, spicy aroma and flavour.
The step that matters
Bake immediately.. Baking soda reacts with the sour milk as soon as it is mixed, releasing gas. If the batter waits, much of that gas escapes before baking, so the cake rises less and may turn out denser.
Swap the ginger
How well each one fits the dish's main ingredients (milk, molasses, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against milk, molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
