Why it works: Raisin and flour 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 Fruit Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 300°F (150°C).
Chop the raisins and slice the citron.
Dust the fruit with flour.
Make the batter
Cream the butter and sugar together.
Add the well-beaten egg yolks to the butter mixture.
Stir in the fruit, then fold in the well-beaten egg whites.
Add the wine and extract, mixing well.
Pour the batter into a prepared baking pan.
Bake
Bake until thoroughly done, about 1 to 1.5 hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Yolks enrich and bind the batter, while whites folded in add lift and a lighter crumb.
- Butter
- Adds fat and richness, giving the cake a tender texture.
- Sugar
- Sweetens the batter and, creamed with butter, helps trap air for a lighter crumb.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
- Wine
- Adds moisture and a subtle acidity and aroma to the batter.
The step that matters
Folding in the egg whites. Whites hold air only when whipped and folded gently; stirring hard deflates them, leaving a denser cake. Flouring the fruit helps keep it from sinking to the bottom.
Swap the vanilla
How well each one fits the dish's main ingredients (raisin, flour, butter, sugar, egg, wine):
- Vanillathe original
- Figfits about as well
- Lemonfits less well
- Applefits less well
Fit is the average pairing score against raisin, flour, butter, sugar, egg, wine. Candidates are from the same food group and used in at least 100 recipes.
