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 ↓
Raisin 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 cake batter
Preheat the oven to 350°F (175°C).
In a bowl, mix together the sugar and melted butter.
Add the sweet milk, flour, baking powder, and lemon flavoring; stir until combined.
Gently fold in the beaten egg whites.
Pour the batter into prepared cake pans.
Bake and make the filling
Bake until golden.
For the filling, combine 1 cup of sugar with a little water in a saucepan and bring to a boil.
Chop the raisins.
Beat the egg white.
Remove the sugar mixture from heat.
Stir in the egg white and raisins.

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
- White sugar
- Sweetens the batter and, when boiled with water, forms the syrup for the filling.
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavor.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas as it heats, helping the cake rise and become light.
- Egg whites
- Beaten and folded in, they add lift and a light, airy texture to the batter.
- Raisins
- Add chewy pieces and concentrated sweetness to the filling.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air bubbles in the whites intact. Stirring vigorously knocks out the air, so the cake rises less and bakes up denser.

Fit is the average pairing score against sugar, butter, milk, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
