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 ↓
Composition 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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the beaten eggs and grated nutmeg, then mix in half of the flour.
Dissolve the baking soda in the milk, strain it, and mix with the brandy.
Stir the milk mixture into the batter along with the remaining flour.
Fold in the raisins just before pouring the batter into the pan.
Bake
Bake in a preheated oven at 350°F (175°C) for 45 minutes to 1 hour.

Flour and butter 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
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Butter
- Creams with sugar to trap air and adds richness and tender texture.
- Eggs
- Bind the batter and help set the crumb while adding richness.
- Baking soda
- Reacts with the acidity in the batter to produce gas that lifts the cake.
- Sugar
- Creams with butter for aeration and adds sweetness and browning.
- Raisins
- Add pockets of sweetness and chewy texture throughout the cake.
The step that matters
Dissolve the baking soda in the milk and add it to the batter. Baking soda needs an acid to react and release gas. Mixing it fully into the liquid and folding it in promptly keeps the rise even, rather than leaving pockets of soda or letting the leavening lose its lift before baking.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, sugar, butter, milk, egg, brandy, raisin):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Allspicefits less well
Fit is the average pairing score against flour, sugar, butter, milk, egg, brandy, raisin. 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.
