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 slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, cream together the sugar, molasses, butter, and egg.
Stir in the baking soda, ground ginger, and vinegar.
Gradually add the flour, mixing until a dough forms.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake at 350°F (175°C) until golden.

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 deep sweetness, moisture, and a dark color to the cookies.
- Butter
- Provides fat for tenderness and richness in the dough.
- All-purpose flour
- Forms the structure that holds the dough and cookie shape together.
- Baking soda
- Reacts with the acidic molasses and vinegar to help the cookies rise and spread.
- Ground ginger
- Contributes the warm, spicy aroma that defines the cookies.
- Sugar
- Adds sweetness and helps the cookies brown during baking.
The step that matters
Stir in the baking soda, ground ginger, and vinegar. Baking soda needs an acid, such as the vinegar and molasses, to release gas and lift the dough. Adding it evenly ensures consistent rising and prevents bitter, patchy spots in the cookies.
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.
