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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and eggs (reserve 3 egg whites for icing) and mix well.
Sift together the flour, baking powder, baking soda, and cream of tartar, then gradually add to the wet mixture.
Divide the batter into three deep jelly tins and bake until a toothpick comes out clean.
Ice and assemble
For the icing, beat the reserved egg whites until stiff, then gradually add the powdered sugar and mix in the grated chocolate and vanilla.
Once the cakes are cool, spread icing between the layers and on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavour.
- Eggs
- Add structure and richness; the whites beaten stiff give the icing its airy body.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes lighter.
- Baking soda
- Reacts with acidic ingredients to produce gas, helping the cake rise and brown.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light, fluffy texture.
The step that matters
Beating the egg whites for the icing. Egg whites must be beaten until stiff without any yolk or grease present, because fat prevents them from holding air. Under-beaten or greasy whites give a loose, runny icing.
