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 ↓
Birthday Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the eggs one at a time, beating well after each addition.
Mix in the milk, fruit, and brandy.
Sift the flour with baking powder, salt, and nutmeg, then add to the mixture.
Bake and finish
Pour into a well-greased and papered cake tin.
Bake in a moderate oven (350°F / 175°C) for two hours.
Turn out and, when cool, cover with white frosting.
Decorate with tiny shamrocks and candles if desired.

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.

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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps hold air for lift and softness.
- Eggs
- Bind the batter and add structure and richness as the cake sets in the oven.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Adds moisture and helps form a smooth, tender batter.
The step that matters
Baking for two hours at moderate heat. A long, moderate bake lets the dense, fruit-filled batter set through the centre without the outside browning or drying too early. Checking doneness before turning out prevents a sunken or gummy middle.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, raisin, brandy):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Allspicefits less well
Fit is the average pairing score against butter, sugar, egg, milk, flour, raisin, brandy. Candidates are from the same food group and used in at least 100 recipes.
