Why it works: Molasses and sugar 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 Snaps, No. 3
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a saucepan, combine molasses, butter, and sugar.
Heat on the stove until it comes to a boil, then remove from heat immediately.
Stir in baking soda and ground ginger.
Add enough flour to form a dough that can be rolled thin.
Shape and bake
Roll out the dough and cut into shapes.
Bake in a 400°F (200°C) oven until lightly browned.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 deep sweetness, moisture, and the dark color and flavor of the cookie.
- Butter
- Provides fat that gives the snaps a tender, crisp texture.
- Sugar
- Sweetens the dough and helps it brown and crisp as it bakes.
- Baking soda
- Reacts with the acidic molasses to lighten the dough and help it spread and darken.
- Ground ginger
- Supplies the spicy aroma that defines the cookie.
- Flour
- Builds the structure so the dough can be rolled thin and hold its cut shapes.
The step that matters
Remove the mixture from heat as soon as it boils. Molasses and sugar darken and harden quickly when overheated. Boiling too long can make the snaps bitter and brittle, so timing matters here.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, sugar, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against molasses, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
