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 ↓
Soft 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
In a bowl, combine molasses, ginger, baking soda, and melted butter.
Pour in the boiling water and mix well.
Gradually add the flour and stir until smooth.
Bake
Pour the batter into a greased pan, filling it one inch deep.
Bake at 350°F (175°C) until a toothpick comes out clean.

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 deep flavor, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the acidic molasses to release gas, lifting the batter and darkening its color.
- Flour
- Provides the structure that sets the batter into a cake-like crumb as it bakes.
- Melted butter
- Adds fat that tenderizes the crumb and gives a softer texture.
- Ginger
- Supplies the warm, spicy aroma that defines the gingerbread flavor.
The step that matters
Judging when it is done. This batter is moist, so the toothpick test shows whether the center has set. Underbaking can leave the middle gummy and sunken, while overbaking dries the soft crumb that makes this gingerbread good.
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.
