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 ↓
Swiss Chocolate Cake
Ingredients
Directions
Make the batter
Combine shortening, salt, and vanilla in a bowl.
Gradually add sugar and cream until light and fluffy.
Add eggs one at a time, beating thoroughly after each addition.
Blend in the melted chocolate.
Sift flour and baking powder together three times.
Add flour alternately with milk to the shortening mixture, beating until smooth.
Bake and frost
Pour batter into two greased and floured 8‑inch layer pans.
Bake in a preheated oven at 350°F (175°C) for 25 to 30 minutes.
Frost with Swiss Chocolate Frosting between layers and on top and sides of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shortening
- Provides fat that tenderizes the crumb and carries the creaming structure.
- Sugar
- Sweetens the cake and, creamed with fat, traps air that helps it rise and lighten.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- Cake flour
- Low-protein flour forms a tender, fine crumb with a soft structure.
- Baking powder
- Releases gas in the batter so the layers rise and become light.
- Milk
- Adds moisture and liquid that hydrates the flour and dissolves the sugar.
- Chocolate
- Adds chocolate flavor and richness, and deepens the cake's color.
The step that matters
Add flour alternately with milk, beating until smooth. Alternating keeps the batter emulsified and limits gluten development. Overbeating after the flour goes in can toughen the crumb, while adding all the liquid at once can make the batter curdle or set uneven.
