Why it works: Cinnamon and nutmeg match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 11,917 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Christmas Spice Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Flour the chopped raisins and set aside.
Dissolve the baking soda in hot water and mix it with the sour cream.
Stir briefly, then add the molasses and mix well.
Make the batter
In a large bowl, combine the sugar, spices, floured raisins, and flour.
Add the sour cream mixture and stir until combined.
Bake
Pour the batter into a greased pan and bake at 350°F (175°C) for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the acidic sour cream and molasses to release gas, helping the cake rise.
- Sour cream
- Adds moisture and acidity that tenderizes the crumb and activates the baking soda.
- Molasses
- Adds moisture, dark color, and a deep sweetness that helps the cake brown.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Adds sweetness and helps keep the cake moist and tender.
The step that matters
Dissolve the baking soda in hot water before mixing with the sour cream. Baking soda must be fully dissolved and combined with the acidic sour cream so it reacts evenly. Clumps can leave bitter spots or uneven rising in the finished cake.
Swap the clove
How well each one fits the dish's main ingredients (raisin, flour, cream, molasses, sugar, cinnamon, nutmeg):
- Cardamomfits about as well
- Allspicefits about as well
- Clovethe original
- Gingerfits less well
Fit is the average pairing score against raisin, flour, cream, molasses, sugar, cinnamon, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
