Why it works: Flour and butter 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 ↓
Hot Water Gingerbread
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Combine molasses and boiling water in a bowl.
In another bowl, mix and sift the flour, baking soda, ground ginger, and salt.
Combine the dry ingredients with the molasses mixture.
Add melted butter and beat vigorously until smooth.
Bake
Pour the batter into a buttered pan.
Bake for 25 minutes in a moderate oven at 350°F (175°C).

Flour and butter 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, dark color and a deep flavor to the gingerbread.
- Flour
- Provides the structure that holds the batter together as it bakes.
- Baking soda
- Reacts with the acidity in molasses to lift and lighten the crumb.
- Melted butter
- Adds fat for tenderness and a moist, rich texture.
- Ground ginger
- Supplies the main spiced aroma that defines the gingerbread.
The step that matters
Beat the batter vigorously until smooth. Thorough beating fully combines the flour with the liquid and fat, so the batter bakes evenly without lumps or dense streaks of unmixed flour.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, flour, butter):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against molasses, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
