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 ↓
Delicious 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 cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk and mix well.
Sift together the flour and baking powder, then gradually add to the mixture.
Fold in the beaten egg whites gently.
Pour the batter into prepared cake pans and bake until a toothpick comes out clean.
Make the icing
For the icing, boil 2 cups of sugar until it reaches a taffy stage.
Remove from heat and add the beaten egg white and grated chocolate.
Beat the icing continuously until it cools and thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Eggs
- Egg whites add structure and lift when beaten and folded into the batter.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown while creaming adds air to the batter.
- German chocolate
- Gives the cake and icing their chocolate flavor.
The step that matters
Beat the icing continuously until it cools and thickens. Sugar syrup that is stirred while it cools forms fine crystals, which makes the icing creamy rather than grainy. Stopping early can leave it runny or let it set coarse.
