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 ↓

Ingredients
Directions
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Combine molasses, butter, and sugar in a saucepan.
Heat until it comes to a boil.
Remove from heat and stir in baking soda and ginger.
Shape and bake
Roll the dough thin and cut into shapes.
Bake in a preheated oven at 400°F (200°C) until crisp.

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
- New orleans molasses
- Adds deep flavour and moisture, and helps the cookies brown and turn chewy-crisp.
- Butter
- Adds fat for tenderness and rich flavour in the dough.
- Sugar
- Sweetens the dough and helps it crisp and brown as it bakes.
- Baking soda
- Reacts with the acidity of molasses to lift and spread the dough.
- Ginger
- Provides the warm, spicy aroma that defines the cookie.
The step that matters
Rolling the dough thin. Thin dough bakes through quickly and crisps evenly. Thick pieces stay soft in the middle and may not reach the crisp texture the recipe calls for.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, sugar):
- Cinnamonfits better
- Gingerthe original
- Nutmegfits about as well
- Clovefits about as well
Fit is the average pairing score against molasses, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
