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 ↓
Molasses Cookies
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat oven to 350°F (175°C).
Make and shape the dough
In a large bowl, mix together the sugar, molasses, butter, hot water, salt, ginger, and baking soda until well combined.
Form the dough into thick rolls.
Slice the rolls and place them on a baking sheet.
Bake
Bake for 10-12 minutes or until lightly browned.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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
- Provides moisture, dark color, and the characteristic deep, sweet flavor of the cookies.
- Butter
- Adds fat for tenderness and richness, and helps the cookies brown during baking.
- Baking soda
- Reacts with the acidic molasses to release gas, helping the cookies rise and spread.
- Sugar
- Adds sweetness and helps the cookies brown and set as they bake.
- Ginger
- Adds warm, spicy aroma and flavor that complements the molasses.
The step that matters
Bake until lightly browned, not longer. Molasses and sugar darken quickly and can turn bitter or hard if overbaked. Pulling the cookies once lightly browned keeps them soft and flavorful.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter):
- Cinnamonfits better
- Gingerthe original
- Nutmegfits about as well
- Clovefits about as well
Fit is the average pairing score against sugar, molasses, butter. Candidates are from the same food group and used in at least 100 recipes.
