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 ↓
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.
Prepare the cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter, then add the milk and mix well.
In a separate bowl, beat the eggs and add to the mixture, reserving 2 egg whites.
Sift together the flour, cream of tartar, and baking soda, then gradually add to the wet ingredients.
Pour the batter into prepared cake pans and bake until a toothpick comes out clean.
Make and finish the frosting
For the frosting, beat the reserved egg whites until stiff, then gradually add sugar and grated chocolate, flavoring with lemon.
Frost the cooled cake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness, and help the batter set as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Butter
- Adds fat for tenderness and flavor in the crumb.
- Sugar
- Sweetens the cake and helps give it a tender, browned crumb.
- Baking soda
- Reacts with the acidity in the batter to produce gas that helps the cake rise.
The step that matters
Beating the reserved egg whites until stiff. Stiff egg whites trap air that lightens the frosting. Under-beaten whites stay runny and won't hold the sugar and chocolate, while over-beaten whites turn dry and grainy.
