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 I
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Mix the sour milk with the baking soda and add to the creamed mixture.
Beat in the eggs one at a time.
Sift together the flour and baking powder, then gradually add to the mixture.
Dissolve the grated chocolate in a small amount of hot water and add to the batter.
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Make the frosting and finish
For the frosting, beat the egg whites until stiff peaks form.
Gradually add the confectioner's sugar and continue to beat until smooth.
Fold in grated chocolate and vanilla to taste, then frost the cooled cake.

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 gives the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Sour milk
- Its acidity reacts with the baking soda to lift the batter and tenderize the crumb.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking to add lift and a lighter texture.
The step that matters
Beat the egg whites until stiff peaks form. Whipped egg whites trap air and hold the frosting's volume and smooth texture. Under-beaten whites stay loose, while over-beaten whites turn dry and grainy.
