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 ↓
Birthday 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.
Prepare
Preheat the oven to 350°F (175°C).
Grease and line the cake pans with parchment paper.
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the currants, flour, candied peel, almonds, spices, and lemon rind, mixing well.
In a separate bowl, beat the eggs and then add them to the mixture along with the brandy.
Pour the batter into the prepared pans and smooth the top.
Bake and cool
Bake for 3 hours or until a toothpick inserted in the center comes out clean.
Let the cake cool completely before icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air, giving a light, tender crumb and richness.
- Eggs
- Bind the batter and add structure and lift as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps create a soft texture when creamed with butter.
- Currants
- Add chewy pockets of fruit sweetness throughout the cake.
The step that matters
Baking time and doneness check. A long bake at moderate heat sets the large batter slowly; testing the center with a toothpick confirms it is cooked through, since an underbaked center will sink and stay gummy.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, almond, lemon, egg, brandy):

Fit is the average pairing score against sugar, butter, flour, almond, lemon, egg, brandy. Candidates are from the same food group and used in at least 100 recipes.
