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 ↓
Chocolate Cookies
Ingredients
Directions
The book says “a hot 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 the butter, sugar, molasses, egg, ginger, baking powder, and baking soda.
Add the dissolved chocolate mixture and mix until stiff.
Sprinkle with sugar before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that tenderizes the cookie and carries flavor.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
- Cake chocolate
- Adds chocolate flavor and color to the dough.
The step that matters
Mixing in the dissolved chocolate until stiff. Chocolate dissolved in boiling water must be fully incorporated so it distributes evenly. Overmixing after adding flour-free wet ingredients is less of a concern here, but stopping too early leaves streaks and an uneven texture.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, molasses, egg, chocolate):
- Cinnamonfits better
- Nutmegfits about as well
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against butter, sugar, molasses, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
