Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix molasses, sugar, butter, and eggs until well combined.
Add baking soda, cloves, allspice, cinnamon, and enough flour to form a dough.
Roll the dough thin and cut into shapes.
Bake and glaze
Place on a baking sheet, giving each cookie space.
Bake until half done, then brush with a glaze made from the yolk of an egg mixed with an equal amount of water and ¼ teaspoon sugar.
Return to the oven and finish baking.

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 a deep, dark flavor to the dough.
- Butter
- Adds fat for tenderness and flavor, and helps the dough hold together.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Baking soda
- Reacts with the molasses acidity to lift the cookies and promote browning.
- Flour
- Provides the structure that lets the dough be rolled and cut into shapes.
The step that matters
Bake until half done before glazing. Glazing too early or leaving the cookies in too long changes the finish. Baking partway first sets the surface so the egg glaze can coat it and brown evenly when returned to the oven.
Swap the clove
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg, allspice, cinnamon, flour):
- Nutmegfits better
- Clovethe original
- Cardamomfits less well
- Gingerfits less well
Fit is the average pairing score against molasses, sugar, butter, egg, allspice, cinnamon, flour. Candidates are from the same food group and used in at least 100 recipes.
