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

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the chocolate mixture

  1. Melt the chocolate with ⅓ cup sugar, ⅓ cup milk, and ½ teaspoon vanilla in a bowl over a tea kettle until smooth.

Make the batter

  1. In another bowl, cream ¼ cup butter with ½ cup sugar.

  2. Add ⅓ cup milk, 1 egg, and ½ teaspoon baking soda to the butter mixture and mix well.

  3. Stir in 1 cup flour and then add the melted chocolate mixture.

  4. Mix until well combined and pour into a greased baking pan.

Bake

  1. Bake in a slow oven at 300°F (150°C) until a toothpick comes out clean.

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

What each ingredient does

All-purpose flour
Provides the structure that holds the cake together as it sets.
Egg
Helps bind the batter and adds structure and richness to the crumb.
Butter
Adds fat for tenderness and a rich, soft texture.
Baking soda
Reacts to create gas bubbles that help the cake rise.
Chocolate
Gives the cake its chocolate flavor and deep color.

The step that matters

Pour the batter into the pan promptly after mixing. Baking soda starts producing gas as soon as it meets the liquid and acid-free batter, so delaying the bake can weaken the rise. Mixing only until combined also avoids overdeveloping the flour's gluten, which would make the cake tough.
