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
Make the chocolate base
Combine ¾ cup Baker's chocolate, 3 egg yolks, 1½ cups brown sugar, and 1 cup milk in a double boiler, then cook until creamy and let cool.
Make the batter
Mix 4 eggs, 2 cups brown sugar, 1 cup butter, and 1 cup milk in a separate bowl. Dissolve 1 teaspoon baking soda in the milk and add to the mixture.
Gradually add 4 cups flour and vanilla extract to the batter.
Make the syrup
Boil 1¼ pounds sugar and ¾ cup water until it ropes, stirring only until dissolved.
Remove from heat and stir until it becomes milky.
Finish the cake
Fold in 2 beaten egg whites and ¼ pound grated chocolate until nearly cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set.
- Flour
- Forms the main structure that holds the cake's crumb together.
- Baking soda
- Reacts with the batter's acid and gas bubbles lift the cake as it bakes.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Brown sugar
- Adds sweetness and moisture, and a deeper caramel flavor.
- Chocolate
- Provides the main chocolate flavor and richness in the cake.
The step that matters
Boil the sugar and water until it ropes. Sugar syrup cooked to the ropes stage has a set concentration. Undercooking leaves it too wet, while overcooking makes it hard and grainy, which changes the cake's texture.
“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.
