Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Imperial 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 your oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, baking soda, mace, and wine.
Fold in the raisins, almonds, and citron until evenly distributed.
Bake
Pour the batter into a greased cake pan.
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and moisture as they set during baking.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
- Flour
- Forms the gluten and starch network that gives the cake its structure.
- Sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Baking soda
- Reacts with the wine's acidity to release gas that helps the cake rise.
The step that matters
Add the eggs one at a time. Adding eggs gradually lets each one emulsify into the creamed butter and sugar. Adding them all at once can cause the batter to curdle and lose its airy structure.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, flour, raisin, almond, egg, wine):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against sugar, butter, flour, raisin, almond, egg, wine. 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.
