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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cook the chocolate with a little milk until smooth.
Beat the egg yolks and sugar together until creamy.
Add the chocolate, then gradually mix in the flour and vanilla.
Fold in the beaten egg whites gently.
Bake and finish
Pour the batter into a square shallow pan and bake at 350°F (175°C).
Frost with white frosting once cooled.
Cut the cake into 2-inch squares.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whipped whites give the cake structure and a light, airy crumb.
- Flour
- Provides the starch and gluten network that sets the batter into a cake structure.
- Powdered sugar
- Adds sweetness and helps give the batter a tender texture.
- Grated chocolate
- Adds chocolate flavor and richness to the batter.
The step that matters
Fold in the beaten egg whites gently. Egg whites hold air that gives the cake its rise. Stirring vigorously deflates the foam, leaving a dense, flat cake, so fold slowly with a spatula until just combined.
“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.
