Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat oven to 400°F (200°C).
In a bowl, mix molasses, sugar, egg, sour milk, and butter until well combined.
Stir in ginger and baking soda.
Gradually add flour until batter is thick enough to pour into a shallow pan.
Bake
Pour batter into prepared pan and bake for about 20-25 minutes or until a toothpick comes out clean.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds deep sweetness, dark colour and moisture to the batter.
- Egg
- Helps bind the batter and gives the crumb structure as it sets.
- Sour milk
- Its acidity reacts with baking soda to help the cake rise and tenderise.
- Butter
- Adds fat for richness and a tender texture.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
- Flour
- Provides the structure that sets the batter as it bakes.
The step that matters
Gradually add flour until batter is thick enough to pour. Too much flour makes the gingerbread dense and dry, while too little leaves it wet and slow to set. Adding flour gradually lets you stop at a pourable but thick consistency.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, egg, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against molasses, sugar, egg, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
