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 ↓
Ginger-bread
Ingredients
Directions
The book says “a very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, beat the eggs and mix in the lard, molasses, brown sugar, and ginger.
Dissolve the baking soda in boiling water and add it to the mixture.
Gradually stir in the flour until well combined.
Bake
Drop tablespoons of the mixture onto a slightly greased baking sheet, spacing them about 3 inches apart.
Bake until golden brown.

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Bind the batter and add structure as they set in the oven.
- Baking soda
- Reacts with the molasses and heat to lighten the cookies and help them rise.
- All-purpose flour
- Forms the main structure that sets as the cookies bake.
- Molasses
- Adds sweetness, moisture, and deep color that contributes to browning.
- Lard
- Adds fat for tenderness and moisture in the baked texture.
The step that matters
Dissolving the baking soda in boiling water. Baking soda needs moisture and heat to react and release gas. Dissolving it fully before mixing spreads the leavening evenly, so the cookies rise uniformly instead of in pockets or patches.
Swap the ginger
How well each one fits the dish's main ingredients (egg, molasses, sugar, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against egg, molasses, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
