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
Preheat the oven to 350°F (175°C).
Cream together 1 cup sugar and ½ cup butter.
Add ½ cup sweet milk, 2 eggs, and 2½ cups flour to the mixture.
Dissolve 1 teaspoon baking soda in hot water and mix it in.
Make the chocolate custard
In a saucepan, heat 1 cup sweet milk and 1 cup grated Baker's chocolate until dissolved.
Stir in 1 cup sugar and the lightly beaten egg yolk.
Combine the chocolate custard with the cake batter when cool.
Bake and layer
Bake in three layers.
Layer the cake with jelly for a tart taste.

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 to the cake crumb.
- Flour
- Forms the main structure of the cake batter.
- Baking soda
- Reacts with the batter to help it rise.
- Butter
- Adds fat for tenderness and flavor in the batter.
- Baker's chocolate
- Gives the cake its chocolate flavor and color in the custard.
- Sugar
- Sweetens the cake and helps brown the crumb.
The step that matters
Combine the chocolate custard with the cake batter when cool.. If the custard is still hot, it can curdle the eggs or thin the batter, changing the cake's texture and rise.
