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.
Make the dough
In a bowl, mix sugar, molasses, butter, egg, vinegar, ginger, and baking soda dissolved in boiling water.
Stir until the mixture forms a soft cookie dough.
Shape the dough into cookies and place them on a baking sheet.
Bake and cool
Bake in a preheated oven at 400°F (200°C) until golden brown.
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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds moisture, deep flavor, and a chewy texture to the cookies.
- Butter
- Provides fat for tenderness and helps the dough spread and brown.
- Baking soda
- Reacts with the acidic vinegar and molasses to lift and lighten the cookies.
- Egg
- Binds the dough and adds structure as the cookies set.
- Sugar
- Sweetens the cookies and helps them brown during baking.
The step that matters
Dissolving the baking soda in boiling water. Baking soda must be fully dissolved so it reacts evenly with the acidic vinegar and molasses. Uneven pockets can cause patchy rising and bitter spots in the cookies.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, egg, vinegar):
- Cinnamonfits better
- Nutmegfits about as well
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against sugar, molasses, butter, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
