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 ↓

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).
Make the batter
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the sour milk and eggs, mixing well.
Stir in the cinnamon, raisins, currants, chopped citron, and baking soda.
Gradually add flour until the batter is stiff.
Bake and assemble
Divide the batter into layers and bake until golden.
Once cooled, layer the cakes with white icing.

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 trap air and add richness and tenderness to the crumb.
- Sugar
- Creams with butter for a light texture and adds sweetness and browning.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that leavens the batter.
- Flour
- Provides the structure that holds the stiff batter and baked layers together.
The step that matters
Gradually add flour until the batter is stiff. Adding flour gradually lets you judge the batter's consistency, since too much flour makes the cake dry and dense while too little leaves it too loose to hold its layers.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, cinnamon, raisin, flour):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against butter, sugar, milk, egg, cinnamon, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
