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.

Make the cake

  1. Preheat the oven to 350°F (175°C).

  2. In a large bowl, cream together the butter and powdered sugar until light and fluffy.

  3. Add the egg whites and mix well.

  4. Sift together the flour and baking powder, then gradually add to the mixture, alternating with the milk.

  5. Stir in the vanilla extract.

  6. Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

Make the icings

  1. For the chocolate icing, melt the Baker's chocolate with ½ cup milk and butter in a saucepan over low heat.

  2. Cook until it thickens, then let it cool and beat until smooth.

  3. For the maple icing, boil the maple syrup and brown sugar together until it forms a soft ball in water.

  4. Pour the hot syrup over the beaten egg whites and beat until cool and fluffy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Add structure and lift to the batter, helping the cake rise and set.
All-purpose flour
Provides the main structure that sets as the cake bakes.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Butter
Adds richness and tenderness through fat creamed with the sugar.
Maple syrup
Adds sweetness and flavor to the maple icing and helps it set soft.

The step that matters

Cooking the chocolate icing. Cooking the chocolate mixture over low heat until it thickens keeps it from scorching or seizing. Beating it only after it cools lets it set smooth and glossy rather than grainy.
