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 ↓
Soda 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).
Rub the butter into the flour.
Add the sugar, raisins, currants, and peel; mix well.
Mix and bake
Dissolve the baking soda in the milk and add it to the mixture.
Mix thoroughly and pour into a buttered tin.
Bake until golden brown.

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.

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
- Flour
- Forms the structure of the cake as the batter sets in the oven.
- Baking soda
- Reacts with the acidity in the batter to produce gas, helping the cake rise.
- Butter
- Rubbed into the flour, it adds richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps brown the crust as it bakes.
- Milk
- Hydrates the flour and dissolves the baking soda, giving the batter its moisture.
The step that matters
Dissolve the baking soda in the milk. Baking soda must be fully dissolved and mixed evenly through the batter so it reacts uniformly. Unmixed pockets can leave bitter, soapy patches and uneven rising.
Swap the currant

- Currantthe original
Fit is the average pairing score against flour, butter, raisin, milk, sugar. 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.
