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 (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
Beat the butter and sugar together until creamy.
Add the beaten eggs, flour, and floured fruit, mixing well.
Stir in the baking powder last.
Blanch and chop the almonds, and shred the orange peel or citron finely.
Mix everything thoroughly.
Bake
Pour the batter into a well-buttered tin lined with buttered paper.
Bake for 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to add richness and a tender crumb.
- Sugar
- Sweetens the cake and helps the creamed butter hold air for a softer texture.
- Eggs
- Bind the batter and add structure as the cake sets.
- Flour
- Forms the main structure of the cake as it bakes.
- Baking powder
- Releases gas in the wet batter and in the oven, helping the cake rise.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
The step that matters
Stir in the baking powder last. Baking powder begins releasing gas as soon as it gets wet and warm. Adding it at the end and mixing just until combined keeps that gas in the batter, so the cake rises well instead of going flat or dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, raisin, orange, almond):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, flour, raisin, orange, almond. Candidates are from the same food group and used in at least 100 recipes.
