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 boiling water.
Mix in the molasses, ginger, and butter.
Add enough flour to form a dough that can be rolled out thin.
Shape and bake
Roll out the dough and cut with a cookie cutter.
Bake in a 400°F (200°C) oven until done.
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.

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 dark color that deepens during baking.
- Baking soda
- Reacts with the acidity of molasses to produce gas that lifts and lightens the dough.
- Butter
- Adds fat that tenderizes the cookie and carries flavor.
- Flour
- Provides the structure that holds the dough together and sets during baking.
- Ground ginger
- Contributes the warm, spicy aroma that defines the cookie.
The step that matters
Add enough flour to form a dough that can be rolled out thin. Adding too much flour makes the dough stiff and the cookies dry and tough, while too little leaves a sticky dough that is hard to roll and 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.
