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, No. 2
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
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter. Add the milk and mix well.
In another bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Fold in the egg whites gently.
Pour the batter into layer cake pans and bake until a toothpick comes out clean.
Make the frosting
For the frosting, boil the egg yolks, ½ cup milk, and 1½ cups sugar until thick like molasses.
Remove from heat and stir in the dissolved or grated chocolate.
Assemble and decorate
Spread the frosting between the layers and frost the top with white frosting.
Decorate with chocolate designs using a pastry bag.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure that holds the cake's crumb together as it bakes.
- Egg whites
- Whipped air and protein give the cake lift and a light, airy texture.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Cream of tartar
- Acidifies the batter and stabilizes the egg whites for a finer, lighter crumb.
- Baking soda
- Reacts with the acidic ingredients to produce gas that helps the cake rise.
The step that matters
Folding in the egg whites. Egg whites hold air that gives the cake its lift. Folding gently keeps that air in; vigorous stirring deflates the batter and leads to a dense cake.
“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.
