Why it works: Cinnamon and clove 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 steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the egg, egg yolks, brown sugar, melted butter, sour milk, and molasses.
Stir in the baking soda, flour, cinnamon, and cloves until well combined.
Pour the batter into square tins.
Bake and frost
Bake until golden brown.
Whip the egg whites and gradually add brown sugar to make frosting.
Frost the buns and cut them into squares.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Molasses
- Adds moisture, dark color, and a deep, sweet flavor.
- Sour milk
- Its acidity reacts with the baking soda to help the buns rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the crumb.
- Flour
- Provides the structure that holds the buns together as they set.
- Brown sugar
- Sweetens the buns and helps keep them moist and tender.
The step that matters
Bake until golden brown. Baking too briefly leaves the centre wet and underset, while overbaking dries the crumb. Golden brown colour signals browning from sugars and proteins, which adds flavour. Watch colour and doneness rather than only the clock.
Swap the clove
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, molasses, flour, cinnamon):
- Nutmegfits better
- Cardamomfits about as well
- Clovethe original
- Allspicefits about as well
Fit is the average pairing score against egg, sugar, butter, milk, molasses, flour, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
