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 Loaf 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
Dissolve the chocolate in boiling water.
Beat the butter until creamy, then gradually add the sugar while continuing to beat.
Add the egg yolks and beat again.
Stir in the milk and melted chocolate.
Add the flour and mix well.
Finish and bake
Beat the egg whites to stiff peaks and gently fold them into the mixture.
Add the vanilla and baking powder, mixing quickly and lightly.
Pour the batter into a greased cake pan and bake at 350°F (175°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Egg whites
- Whipped to stiff peaks, they trap air that lifts the cake and gives it a light texture.
- Egg yolks
- Add fat and emulsifiers that enrich the batter and help it hold together.
- Flour
- Its proteins and starch form the cake's structure as the batter sets in the oven.
- Baking powder
- Releases gas in the heated batter, helping the cake rise.
- Chocolate
- Provides the chocolate flavour and some moisture and richness to the crumb.
The step that matters
Folding in the egg whites. Whipped whites hold the air that lifts the cake. Stirring them in vigorously or overmixing after the flour and baking powder deflates the foam and toughens the crumb, so fold gently until just combined.
