Chocolate Cake

Ingredients

Directions

Make the chocolate base

  1. 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 syrup

  1. Boil 1¼ pounds sugar and ¾ cup water until it ropes, stirring only until dissolved.

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.
