Why it works: Molasses and ginger are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 4,116 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix lard, baking soda, molasses, water or milk, and ginger together.
Gradually add flour until well combined.
Shape and bake
Roll out the dough and cut with a 3-inch scalloped cutter.
Wash the tops with water.
Bake in a hot oven at 400°F (200°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.

Shared aroma: methyl 2-methylbutyrate (fruity, apple).
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
- Flour
- Provides the structure that holds the cookies together as they bake.
- Lard
- Adds fat that keeps the cookies tender and short in texture.
- Molasses
- Adds sweetness, moisture, and dark color, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts and lightens the cookies.
- Ginger
- Adds the warm, spicy aroma that defines the cookie.
The step that matters
Gradually add the flour until just combined. Flour proteins form gluten when worked. Overmixing once the flour is in develops too much gluten, making the cookies tough instead of tender.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, milk, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against molasses, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
