Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Cake
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and add the sugar.
Beat in the eggs and milk.
Mix the baking powder with the flour and gradually add to the mixture.
Dissolve the chocolate in the boiling milk and add it last.
Pour the batter into three shallow round tins.
Bake and finish
Bake for about one hour.
Spread with jam, lemon cheese mixture, or chocolate mixture, and stack the cakes.
Ice the top and decorate with glace cherries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure as they set in the oven.
- Flour
- Forms the main structure of the cake as the batter sets.
- Baking powder
- Releases gas in the heat, helping the cakes rise and become light.
- Chocolate
- Adds chocolate flavour and richness to the batter.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed.
The step that matters
Adding the baking powder and flour. Mixing flour gradually into the batter keeps it smooth and evenly combined, and avoiding overmixing helps prevent a tough crumb while the leavening still lifts the cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
