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
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 together the sugar and butter.
Add the flour, milk, and baking powder; mix well.
Fold in the egg whites gently until combined.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
Make the icing
For the icing, melt the chocolate with ½ cup of milk and 1 cup of sugar over low heat.
Stir in the walnut-sized butter and let cool.
Flavor the icing with vanilla before spreading it on the cooled cake.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add tenderness and richness to the cake.
- Egg whites
- Provide structure and lift to the batter when folded in.
- Baking powder
- Releases gas during baking so the cake rises.
- Flour
- Forms the main structure of the cake as the batter sets.
- Sugar
- Adds sweetness and helps the cake brown and stay moist.
The step that matters
Fold in the egg whites gently. Egg whites hold air that gives the cake its lift. Stirring vigorously knocks that air out, leaving a denser cake.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, flour, milk, egg, chocolate, vanilla):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against sugar, butter, flour, milk, egg, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
