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 ↓

Ingredients
Directions
Make the batters
Whisk together 5 cups butter, 1 cup red sugar, 1 cup sweet milk, 3 cups flour, 2 teaspoons baking powder, whites of 4 eggs, and 1 teaspoon vanilla.
Whisk together 2 cups butter, 1 cup red sugar, 1 cup sweet milk, 2 cups flour, 2 teaspoons baking powder, 1 cup seedless raisins, 1 teaspoon vanilla, and yolks of 4 eggs.
Assemble and bake
Place a tin or pasteboard ring, round or oval, a little larger than half the size of the pan, in the centre of the pan, fill it with the red mixture, and pour the white mixture around it.
Butter the ring so it will lift out.
Bake in a slow oven.

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.

Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 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 that makes the crumb tender and rich.
- Eggs
- Whites add lift and structure; yolks add richness and colour.
- Flour
- Forms the structure that holds the cake together as it sets.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Red sugar
- Adds sweetness and helps the crumb brown.
- Seedless raisins
- Adds chewy pockets of sweetness in the red batter.
The step that matters
Keeping the two batters separate. Placing the ring in the centre and pouring the white batter around it keeps the red and white mixtures apart, creating the two-tone pattern. The ring must be buttered so it lifts out cleanly without tearing the batter.

Fit is the average pairing score against butter, milk, flour, vanilla, sugar, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
