Why it works: Cinnamon and ginger match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,380 recipes. Both carry estragole, which smells anise, licorice. 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.

Prepare

Sift the dry ingredients together: flour, baking soda, salt, cinnamon, and ginger.
In a separate bowl, mix the molasses, egg, and melted butter.

Mix and bake

Combine the wet and dry ingredients until well mixed.
Pour the batter into a greased baking pan.
Bake at 350°F (175°C) for about 30 minutes.

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, dark color, and moisture to the batter.
Egg: Helps bind the batter and gives the crumb structure.
Melted butter: Adds fat for a tender texture and moisture.
Baking soda: Reacts with the molasses acidity to help the gingerbread rise.
Flour: Provides the main structure as the batter sets in the oven.
