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 ↓
Ginger Cookies
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 the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix sugar, molasses, butter, egg, vinegar, ginger, and baking soda dissolved in boiling water until combined.
Gradually add flour to form a soft dough.
Roll the dough out to a thinness similar to wafers.
Bake and cool
Bake in the preheated oven until lightly browned, ensuring they do not burn.
Allow cookies to cool completely before storing.

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 moisture, dark color and a deep sweetness to the dough.
- Butter
- Adds fat for tenderness and helps the cookies spread and crisp.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Baking soda
- Reacts with the acidic molasses and vinegar to lighten the cookies and aid browning.
- Flour
- Provides the main structure that holds the cookies together as they bake.
- Sugar
- Adds sweetness and helps the cookies brown and crisp in the oven.
The step that matters
Bake until lightly browned, not burned. Thin dough cooks quickly, and sugars and molasses scorch easily at high heat. Removing the cookies once they are lightly browned keeps them crisp and avoids bitterness.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, egg, vinegar, flour):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against sugar, molasses, butter, egg, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
