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 says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare and bake
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and sugar until well combined.
Add flour, milk, and baking powder; mix until smooth.
Pour the batter into two 4x9 inch baking tins.
Bake until done, then cut into 1½ inch squares.
Make the chocolate mixture
For the mixture, boil grated chocolate, sugar, and water until it reaches a hair stage.
Add the mixture to the beaten egg whites.
Finish
Roll the squares in the chocolate mixture, then in powdered sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar to trap air, giving the cake structure and lift.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking powder
- Releases gas in the batter, causing it to rise and become light.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Milk
- Adds moisture and softness to the batter.
- Grated chocolate
- Gives the coating its chocolate flavor and rich color.
The step that matters
Boil the chocolate mixture to the hair stage. The sugar syrup must reach the right concentration. Stopping too early leaves the coating runny and sticky, while boiling too long makes it hard and grainy as it cools.
