Why it works: Cinnamon and nutmeg match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 11,917 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Crumb Ginger Bread

Oven, in the book's wordsA moderate oven

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.

Prepare the batter

In a large bowl, mix flour, sugar, and butter until fine crumbs form.
Set aside 2 cups of the crumb mixture.
To the remaining crumbs, add beaten eggs, buttermilk, baking soda, ginger, cinnamon, and nutmeg. Mix well.

Layer and bake

Grease a baking pan and sprinkle 1 cup of crumbs in the bottom.
Pour the batter over the crumbs and top with the remaining cup of crumbs.
Bake in a moderate oven at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour: Forms the structure of the crumbs and sets the crumb texture as the bread bakes.
Butter: Adds fat that coats the flour and gives the crumbs richness and tenderness.
Eggs: Bind the batter and help set the crumb structure during baking.
Buttermilk: Adds moisture and acidity that keeps the crumb tender and reacts with the baking soda.
Baking soda: Reacts with the buttermilk's acidity to produce gas that helps the bread rise.
Sugar: Adds sweetness and helps the top brown to a golden color.
