Why it works: Sugar and molasses 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 says “a 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 dough
In a bowl, mix sugar, molasses, lard, egg, ginger, and vinegar.
Dissolve baking soda in the vinegar and add to the mixture.
Gradually add flour and knead until smooth.
Shape and bake
Roll out the dough to your desired shape.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds deep sweetness, moisture and the dark colour of the cookie.
- Flour
- Provides the structure that holds the dough together as it is kneaded and baked.
- Lard
- Adds fat for tenderness and a short, crisp texture.
- Baking soda
- Reacts with the acidic vinegar and molasses to lighten the dough and help it spread and brown.
- Sugar
- Sweetens the dough and helps it brown and crisp in the oven.
The step that matters
Dissolve baking soda in the vinegar. Baking soda needs an acid to react and release gas. Dissolving it fully in the vinegar before adding it spreads the reaction evenly, so the cookies rise and brown evenly rather than in patches.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, egg, vinegar, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits about as well
- Gingerthe original
Fit is the average pairing score against sugar, molasses, egg, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
