Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ginger Cookies

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 dough

In a bowl, mix molasses, egg, brown sugar, and butter until well combined.
Add baking soda and ground ginger, mixing thoroughly.
Gradually add flour until the dough is firm enough to roll.

Shape and bake

Roll out the dough on a floured surface and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 deep, sweet flavor to the cookies.
Egg: Binds the dough and adds structure as the cookies set.
Brown sugar: Adds sweetness, moisture and a soft texture.
Butter: Adds fat for tenderness and richness in the dough.
Baking soda: Reacts with the molasses's acidity to lift the dough and aid browning.
Ground ginger: Provides the warm, spicy aroma that defines the cookies.
