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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Melt the chocolate with the milk in a pan of water and let it cool.
Dissolve the baking soda in boiling water and let it stand.
Cream the shortening, salt, and sugar together until well combined.
Add the beaten eggs and mix well.
Stir in the chocolate mixture and vanilla.
Add the dissolved baking soda.
Alternately mix in the flour and milk, beating well after each addition.
Bake
Pour the batter into two cake pans and bake at 350°F (175°C) for 30 to 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking soda
- Reacts with the chocolate and batter to help the cake rise and darken.
- Shortening
- Creams with sugar to trap air and give the cake a tender texture.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Baker's chocolate
- Provides the chocolate flavor and deep color of the cake.
The step that matters
Dissolve the baking soda in boiling water. Baking soda needs to be fully dissolved so it reacts evenly through the batter. Undissolved pockets can leave bitter spots or uneven rising.
