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 gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a bowl, combine sugar and butter until creamy.
Dissolve baking soda in boiling water and add to the mixture.
Stir in molasses and ginger until well combined.
Bake
Mix until soft and bake in a slow oven at 300°F (150°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Butter
- Adds fat that makes the cookies rich and tender.
- Sugar
- Adds sweetness and helps the cookies brown and stay moist.
- Molasses
- Adds moisture, deep sweetness, and dark color, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the molasses acid to produce gas that lifts and softens the cookies.
- Ginger
- Provides the warm, spicy aroma and flavor that defines the cookies.
The step that matters
Dissolving the baking soda in boiling water. Baking soda must be fully dissolved and evenly distributed through the dough. Clumps can leave bitter, soapy spots and uneven rising, because the soda only lifts the dough where it reacts with the molasses acid.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, butter, molasses):
- Cinnamonfits better
- Gingerthe original
- Nutmegfits about as well
- Clovefits about as well
Fit is the average pairing score against sugar, butter, molasses. Candidates are from the same food group and used in at least 100 recipes.
