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 ↓
Devil 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 custard
Combine grated chocolate, sweet milk, brown sugar, egg yolk, and vanilla in a saucepan; cook slowly over low heat until thickened, then set aside to cool.
Make the batter
Cream butter and brown sugar in a mixing bowl; add egg yolks and mix well.
Stir in milk and sifted flour until combined.
Fold in stiffly beaten egg whites.
Gently mix in the cooled custard and add baking soda dissolved in warm water.
Pour the batter into a greased loaf pan or jelly tins.
Bake and rest
Bake at 350°F (175°C) until a toothpick comes out clean.
For best flavor, prepare at least one week before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites are folded in for lift, and yolks add richness and structure to the batter.
- Flour
- Provides the structure that holds the cake's crumb once baked.
- Butter
- Creamed with sugar to trap air and add fat for a tender texture.
- Brown sugar
- Adds sweetness, moisture, and a caramel note to the cake and custard.
- Grated chocolate
- Gives the cake its chocolate flavor and deep color in the custard.
- Baking soda
- Reacts with the batter to help it rise and promotes browning.
The step that matters
Cooking the custard slowly over low heat. Chocolate and egg yolk can scorch or curdle if heated too quickly. Gentle heat lets the mixture thicken smoothly before it is cooled and folded into the batter.
