Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a large bowl, combine molasses, brown sugar, thick milk, lard, ginger, and dissolved baking soda. Mix well until combined.
Gradually add flour until the dough is manageable.
Cover the bowl and let the mixture sit overnight.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until golden.

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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 sweetness, dark color, and a moist, chewy texture to the cakes.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts and lightens the dough.
- Lard
- Adds fat that tenderizes the crumb and carries flavor.
- Flour
- Provides the structure that holds the dough together for rolling and cutting.
The step that matters
Dissolving the baking soda before mixing. Baking soda must be fully dissolved so it reacts evenly with the acidic molasses. Unevenly distributed soda can leave pockets that rise unevenly or taste bitter.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, milk, flour):
- Cinnamonfits better
- Nutmegfits about as well
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
