Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, butter, eggs, cream of tartar, baking soda, milk, and vanilla until smooth.
Divide the batter into three medium-sized jelly tins.
Make the filling
In a saucepan, combine grated chocolate, 1 cup milk, cornstarch, egg yolk, and sugar; boil until thick.
Spread the chocolate mixture between the cakes and around the sides, extending it about 1 inch.
Frost
Whip the egg white and use it to frost the top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set during baking, binding the batter.
- Flour
- Forms the structure of the cake crumb as it bakes.
- Sugar
- Adds sweetness and helps keep the cake tender and moist.
- Baking soda
- Reacts with the acid in the batter to produce gas, helping the cake rise.
- Cream of tartar
- Acidifies the batter, stabilizing the egg foam and helping the rise.
- Grated chocolate
- Gives the filling its chocolate flavor and body.
The step that matters
Boil the chocolate filling until thick. Cornstarch and egg yolk thicken the filling only when it reaches a full boil. Undercooked, it stays runny and can soak into the cake layers.
