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 Caramel 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 350°F (175°C).
Beat the egg yolks and whites separately until fluffy.
In a bowl, cream together the butter and powdered sugar.
Add the sweet cream and chocolate to the creamed mixture.
Gradually mix in the flour and baking powder.
Fold in the beaten egg whites and vanilla.
Pour the batter into a greased cake pan and bake for 25-30 minutes.
Make the filling
For the filling, boil the white sugar with a small amount of water until it ropes.
Beat the whites of 3 eggs to stiff peaks.
Slowly pour the hot sugar into the egg whites while stirring constantly until cool.
Add the citric acid and mix well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake lift and an airy, light crumb.
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Flour
- Forms the cake's structure once mixed with the batter.
- Baking powder
- Releases gas in the oven, helping the cake rise.
- White sugar
- Cooked to a rope stage to form the sweet, set caramel-style filling.
- Chocolate
- Adds chocolate flavour and richness to the batter.
The step that matters
Pouring the hot sugar into the egg whites. Hot syrup must be poured slowly while whisking constantly so it blends smoothly and cooks the whites without scrambling them or deflating the foam.
