Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Make the dough
Dissolve the baking soda in the boiling water.
In a bowl, combine the molasses, ginger, and butter.
Add the dissolved soda mixture and mix well.
Gradually add flour until the dough is thin enough to roll out.
Shape and bake
Cut into shapes with a cookie cutter.
Bake in a preheated oven at 400°F (200°C) until done.

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 sweetness, moisture, and a deep flavor that keeps the cookies chewy.
- Baking soda
- Reacts with the acidic molasses to produce gas, which helps the cookies rise and spread.
- Butter
- Adds fat that gives the cookies tenderness and a rich mouthfeel.
- Ground ginger
- Provides the warm, spicy aroma that defines the cookie's flavor.
- Flour
- Provides the structure that holds the cookies together once the dough is rolled out.
The step that matters
Gradually add flour until the dough is thin enough to roll out. Adding flour gradually lets you stop at the right consistency. Too much flour makes the dough stiff and the cookies dry and tough, while too little leaves it sticky and hard to cut cleanly.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
