Why it works: Vanilla and milk 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.
Make the batter
Dissolve the chocolate in 2 tablespoons of milk.
Cream the butter and sugar together.
Add the eggs and a little flour to the mixture.
Stir in the dissolved chocolate, remaining flour, and baking powder.
Add a few drops of vanilla essence.
Bake and finish
Pour the mixture into a greased baking tin.
Bake in a moderate oven at 350°F (175°C) for about 1 hour.
Ice the cake with chocolate icing when cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and lift as they set in the oven.
- Butter
- Adds richness and tenderness by coating flour and trapping air when creamed with sugar.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Baking powder
- Releases gas in the batter so the cake rises and becomes lighter.
- Chocolate
- Gives the cake its chocolate flavour and adds moisture and depth.
The step that matters
Creaming the butter and sugar together. Beating them until light and fluffy traps air bubbles that help the cake rise and give it a tender crumb. Under-creamed butter leaves a dense cake.
