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 ↓
Plain Gingerbread
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 batter
Partly melt the butter.
Stir the melted butter into the molasses.
Add the ground ginger and boiling water, mixing smoothly.
Stir in the prepared flour until well combined.
Bake
Pour the batter into a buttered baking pan.
Bake in a 400°F (200°C) oven for about 30 minutes.
Check for doneness with a broom straw; it should pass through without sticking.

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
- Provides the dark color, rich flavor and moisture that characterize gingerbread.
- Prepared flour
- Forms the structure that sets the batter as it bakes.
- Butter
- Adds fat for a tender crumb and richer flavor.
- Ground ginger
- Supplies the characteristic spicy aroma of the cake.
The step that matters
Testing for doneness with a broom straw. Gingerbread is moist and sticky, so the center can look set while still being underbaked. A straw that comes out clean, without wet batter clinging to it, shows the starches have set and the cake is fully baked.
Swap the ginger
How well each one fits the dish's main ingredients (butter, molasses, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against butter, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
