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 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 batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sweet milk and vanilla.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry mixture to the wet mixture.
Melt the chocolate with the milk.
Add the melted chocolate to the batter.
Beat the egg whites until very light.
Fold the beaten egg whites into the batter.
Bake and ice
Pour the batter into a greased cake pan.
Bake at 350°F (175°C) until a toothpick comes out clean.
For the icing, combine brown sugar, cream, and butter in a saucepan.
Boil until it forms a soft ball when tested in cold water.
Spread the icing over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites add lift and a light, airy crumb; yolks add richness and structure.
- Baking powder
- Releases gas in the batter, causing the cake to rise and become tender.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Butter
- Creamed with sugar to trap air and add fat for a tender texture.
- Brown sugar
- Adds moisture and deep caramel flavor to the icing and helps it set soft.
- Chocolate
- Adds flavor and color to the batter.
The step that matters
Boiling the icing to soft ball stage. Sugar syrup must reach the right temperature to set correctly; too little boiling leaves the icing runny, while too much makes it hard and grainy as it cools.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, chocolate, cream):
- Almondfits better
- Hazelnutfits about as well
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against butter, sugar, egg, milk, flour, chocolate, cream. Candidates are from the same food group and used in at least 100 recipes.
