Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Caramel Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg whites until stiff.
In another bowl, cream together the butter and sugar.
Gradually add the flour, sweet milk, and baking powder to the butter mixture.
Fold in the beaten egg whites gently.
Pour the batter into jelly pans and bake until golden.
Make the filling
For the filling, combine brown sugar and sweet milk in a saucepan over medium heat.
Once boiling, add the butter and boil until it drops from a spoon.
Stir in the pecans and cook for a few more minutes.
Remove from heat and beat until thick enough to spread between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they lighten the batter and help the cake rise.
- Butter
- Creamed with sugar, it adds tenderness and richness to the cake and body to the filling.
- Sugar
- Creamed with butter, it sweetens the cake and helps give it a tender, even crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Brown sugar
- Cooked with milk and butter, it gives the filling its caramel flavor and thickness.
The step that matters
Beating the filling until thick. The filling must be beaten off the heat until it cools and thickens enough to spread. Spreading it too soon leaves it runny and it may soak into the layers.
Swap the pecans
How well each one fits the dish's main ingredients (egg, butter, sugar, flour, milk):
- Almondfits better
- Chestnutfits about as well
- Milletfits about as well
- Pecansthe original
Fit is the average pairing score against egg, butter, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
