Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Imperial 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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the essence of almond.
Gradually mix in the flour, adding a little milk if the batter is too thick.
Layer and bake
Pour half of the batter into a wooden frame.
Layer the next mixture (from the next recipe) over the batter.
Spread the remaining batter evenly on top.
Gently knock the tin to help the batter settle around the fruit.
Bake in a moderate oven at 350°F (175°C) until done.
Finish
Once baked, ice the cake with white fondant icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air, giving the cake a light, tender crumb and rich flavour.
- Eggs
- Provide structure as they set in the oven and add richness and moisture to the batter.
- Prepared flour
- Forms the main structure of the cake as its starches set during baking.
- Sugar
- Sweetens the batter and helps create a light texture when creamed with butter.
The step that matters
Adding the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the creamed butter and sugar. Adding them all at once can cause the batter to curdle, which affects the final texture.
“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.
