Why it works: Cinnamon and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,536 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Old Fashioned Layer Cake
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually add the flour and baking powder, alternating with the milk.
Divide the batter into three parts.
To one part, add the molasses and spices, mixing in a little more flour if needed.
Pour the plain batter into two greased cake pans and the spiced batter into one.
Bake and cool
Bake for 25-30 minutes or until a toothpick comes out clean.
Let the cakes cool before frosting.
Frost and assemble
For the frosting, beat the egg whites until stiff peaks form.
Gradually add the sugar, lemon zest, and lemon juice, beating until smooth.
Frost the layers, placing the spiced layer in the middle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a tender, fine texture and rich flavor.
- Eggs
- Add structure and richness, helping the batter set and hold its rise in the oven.
- All-purpose flour
- Forms the cake's main structure once mixed with liquid and heated.
- Baking powder
- Releases gas in the batter, helping the layers rise as they bake.
- Molasses
- Adds moisture, dark color, and a deep, slightly bittersweet flavor to the spiced layer.
- Egg whites
- Whipped to stiff peaks to form the airy structure of the frosting.
The step that matters
Beat the egg whites until stiff peaks form. Egg whites hold air only when fully whipped and free of fat; underwhipped or greasy whites will not stiffen, leaving a runny frosting that does not hold its shape.
Swap the allspice
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, molasses, cinnamon):
- Nutmegfits better
- Cardamomfits about as well
- Clovefits about as well
- Allspicethe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, molasses, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
