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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk and egg yolks, mixing well.
Combine the flour and baking powder.
Add the dry mixture to the batter.
Fold in the grated lemon peel.
Beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the batter.
Bake
Pour the batter into a greased jelly tin.
Bake for about 30-35 minutes.
Make the chocolate icing and assemble
Melt 1/3 cup of chocolate in a small tin cup on the back of the stove.
Make a stiff icing with the egg whites and sugar.
Add the melted chocolate and flavor with vanilla.
Spread the icing on the layers and on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Yolks add richness and structure; whites beaten to stiff peaks lighten the batter and help it rise.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise and become airy.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a fine, soft texture.
- Chocolate
- Adds chocolate flavor and color to the icing.
The step that matters
Folding in the beaten egg whites. Beaten egg whites hold air that makes the cake light. Stirring them in vigorously deflates the foam, leading to a dense cake, so fold gently until just combined.
