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 ↓
Molasses Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a mixing bowl, stir together molasses, brown sugar, softened butter, egg, cinnamon, ginger, cloves, allspice, mace, and salt.
Sift in flour and cream of tartar.
Add the steamed raisins.
Dissolve baking soda in warm water and add to the mixture.
Stir lightly but thoroughly, then pour into a greased shallow pan lined with paper.
Bake
Bake for 1 hour in a moderate oven (350°F or 175°C).
The cake is done when a broom straw comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds deep sweetness, dark color, and a moist, rich flavor to the cake.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Egg
- Helps bind the batter and gives structure to the crumb.
- Flour
- Forms the main structure of the cake as it sets in the oven.
- Baking soda
- Reacts with the acidic molasses and cream of tartar to lift the batter as it bakes.
- Cream of tartar
- Acidifies the batter so baking soda reacts properly, helping the cake rise and stay tender.
The step that matters
Stirring the batter. Stir lightly but thoroughly. Overmixing after the flour goes in develops gluten, which can make the cake tough and dense, while the baking soda and cream of tartar need even distribution to rise evenly.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg, cinnamon, clove, allspice):
- Nutmegfits better
- Gingerthe original
- Cardamomfits about as well
- Thymefits less well
Fit is the average pairing score against molasses, sugar, butter, egg, cinnamon, clove, allspice. Candidates are from the same food group and used in at least 100 recipes.
