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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
Gradually stir in the flour and baking powder.
Pour the batter into jelly tins and bake until golden.
Make the caramel filling
For the caramel, combine sugar, sweet milk, egg yolk, and grated chocolate in a saucepan.
Stir over heat until thickened, then let cool before spreading between the cake layers.
Finish
Ice the top with vanilla-flavored icing.

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
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Butter
- Adds fat for tenderness and flavor in the cake.
- Flour
- Forms the structure of the cake as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises.
- Egg yolk
- Thickens the caramel filling as it cooks.
The step that matters
Stir the caramel over heat until thickened. Egg yolk thickens when heated but can scramble if the heat is too high or stirring stops. Stirring gently over moderate heat keeps the filling smooth and lets it set properly as it cools.
