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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat your oven to 400°F (200°C).
In a bowl, mix together the sugar, molasses, and butter until well combined.
Add the ginger and egg, mixing until smooth.
Dissolve the baking soda in the hot water and add it to the mixture.
Add salt to taste and stir until fully incorporated.
Bake
Drop spoonfuls of the dough onto a baking sheet.
Bake in the preheated oven until golden brown.

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.

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
- Adds sweetness, moisture and a dark color to the dough.
- Butter
- Adds fat for tenderness and helps the cookies spread and brown.
- Baking soda
- Reacts with the molasses acid to help the cookies rise and spread.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Ginger
- Provides the warm, spicy aroma that defines the cookie.
The step that matters
Dissolve the baking soda fully in the hot water. Baking soda must be evenly dispersed to react with the acidic molasses. Undissolved clumps leave bitter, soapy pockets and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against sugar, molasses, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
