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 ↓
Old Fashioned Ginger Bread
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a coffee cup, combine melted butter, baking soda, ground ginger, and hot water.
Fill the cup with molasses and stir to combine.
Gradually add flour until a dough forms.
Shape and bake
Roll the dough to about 1 inch thick.
Bake in a moderate oven at 350°F (175°C) until done.

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 dark color, moisture and a rich, slightly bitter sweetness.
- Baking soda
- Reacts with the molasses acidity to lighten the crumb and help it rise.
- Flour
- Provides the structure that holds the dough together and sets as it bakes.
- Melted butter
- Adds fat for tenderness and a smooth, moist texture.
- Ground ginger
- Supplies the warm, spicy aroma that defines gingerbread.
The step that matters
Add the baking soda to the wet mixture before the flour. Baking soda must dissolve and react with the acidic molasses to produce gas for lift. Mixing it fully into the liquids first spreads the reaction evenly so the gingerbread rises uniformly rather than in patches.
Swap the ginger
How well each one fits the dish's main ingredients (butter, molasses, coffee, flour):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Gingerthe original
Fit is the average pairing score against butter, molasses, coffee, flour. Candidates are from the same food group and used in at least 100 recipes.
