Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Balls
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 and bake the cake
Preheat oven to 350°F (175°C).
In a bowl, mix eggs, sugar, flour, milk, and baking powder until smooth.
Divide batter into two greased 4x9 inch tins.
Bake until done, then cut into 1½ inch squares.
Make the chocolate coating
Boil grated chocolate, sugar, and water until it reaches a hair-like consistency.
Remove from heat and add to beaten egg white.
Coat and finish
Roll squares in chocolate mixture, then in powdered sugar.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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 moisture while helping the cake rise.
- Flour
- Forms the main structure that holds the cut squares together.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Baking powder
- Releases gas during baking so the batter rises and becomes light.
- Grated chocolate
- Provides chocolate flavor and a dark color to the coating.
- Egg white
- Adds body and a light, airy texture to the chocolate coating.
The step that matters
Boiling the chocolate, sugar, and water to a hair-like consistency. Sugar syrup must reach the right concentration. Too little cooking leaves the coating runny and it will not cling. Overcooking makes it stiff and brittle as it cools.
