Why it works: Nutmeg and cinnamon 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 ↓
Prune 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream together the sugar and butter‑lard mixture.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour milk and baking soda.
In a separate bowl, combine the flour, nutmeg, and cinnamon.
Gradually add the dry ingredients to the wet mixture.
Fold in the stewed prunes.
Bake
Pour the batter into a greased cake pan and bake for 25‑30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness, helping the batter set into a sturdy crumb.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the cake and lightens its texture.
- Butter and lard
- Add fat that tenderises the crumb and carries flavour.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Stewed prunes
- Add moisture and natural sweetness, keeping the cake soft.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with fat.
The step that matters
Stir in the sour milk and baking soda. Baking soda needs an acid such as sour milk to react and release gas. Adding it late, or letting the batter stand too long before baking, lets the gas escape and leaves the cake flat and dense.
