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 ↓

Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter until smooth.
Add the sugar and mix well.
Beat in the egg.
Dissolve the baking soda in the sour milk and add to the mixture.
Gradually stir in the flour and then fold in the chopped raisins.
Bake
Pour the batter into a greased baking pan.
Bake in a slow oven at 300°F (150°C) until a toothpick comes out clean.

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
- Adds fat and richness, giving the cake a tender crumb and flavor.
- Sugar
- Adds sweetness and helps create a tender texture and browning.
- Egg
- Binds the batter and adds structure as the cake sets in the oven.
- Baking soda
- Reacts with the acidic sour milk to produce gas that helps the cake rise.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
- Flour
- Provides the structure that holds the cake together as it bakes.
The step that matters
Dissolve the baking soda in the sour milk and add to the mixture.. Baking soda needs an acid to react; dissolving it fully in the sour milk lets it react evenly, so the cake rises uniformly rather than in patches.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
