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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the butter and sugar.
Add the eggs and mix well.
Stir in the milk and vanilla.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
Fold in the melted chocolate.
Bake
Pour the batter into a greased cake pan.
Bake for 40 minutes or 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
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Butter
- Adds fat for tenderness and flavour, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Melted chocolate
- Adds chocolate flavour and deep colour to the batter.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing only until combined limits gluten development, keeping the cake tender rather than tough and dense.
