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
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 and bake until golden.
Make the filling
For the filling, combine 1 cup of sugar with a little water in a saucepan and bring to a boil.
Chop the raisins and beat the egg white.
Remove the sugar mixture from heat and stir in the raisins and beaten egg white.

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
- Egg whites
- Whipped and folded in to lighten the batter and give the cake its airy structure.
- Flour
- Forms the main structure of the cake once it sets in the oven.
- Butter
- Adds fat for tenderness and a rich flavor in the crumb.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- White sugar
- Sweetens the batter and helps the cake brown as it bakes.
The step that matters
Fold in the beaten egg whites gently. Egg whites hold air only while they are beaten. Heavy stirring knocks that air out, so the cake bakes up flatter and denser.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, raisin):

- Coconutfits about as well
- Lemonthe original
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.
“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.
