Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Ice Cream 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
Cream the butter and sugar together.
Add the eggs one at a time, mixing well.
Stir in the flour and baking powder.
Add melted chocolate until the desired color is achieved.
Bake in layers at 350°F (175°C).
Make the filling and assemble
For the filling, boil the sugar and water until it forms a candy when dropped in cold water.
Pour the boiling syrup into the beaten egg whites and beat until firm.
Flavor with vanilla and spread between the layers and on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the cake tender and rich.
- Eggs
- Provide structure and help bind the batter as it bakes.
- Flour
- Forms the structure of the cake crumb.
- Baking powder
- Releases gas during baking so the layers rise.
- Egg whites
- Whipped with hot syrup to create a light, stable filling.
The step that matters
Pour the boiling syrup into the beaten egg whites. The syrup must be hot enough to cook the whites slightly as it is beaten in, which stabilizes the foam. Pouring it in slowly while beating keeps the mixture from deflating and helps it set firm.
