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 Roll Pudding
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
Beat the egg whites to a stiff froth, then add the yolks.
Mix in the sugar and flour until well combined.
Dissolve the soda in the cold water and stir into the mixture.
Pour the batter into a buttered pan and bake for 12-15 minutes.
Sprinkle the top with milk after baking.
Make the frosting
For frosting, beat 6 egg whites to a froth and divide into two parts.
Add 1 teaspoon of sugar to one half and 1 teaspoon of sugar plus 3 tablespoons of grated chocolate to the other half.
Spread half of each frosting mixture over the baked cake.
Return to the oven for 5 minutes to harden the frosting.
Roll and finish
Remove from the oven and roll up the cake.
Frost the top and sides of the roll with the remaining frosting.
Return to the oven to harden the frosting again.
Transfer to a flat dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a stiff froth, they give the cake and frosting their airy structure.
- Egg yolks
- Add richness and tenderness to the batter.
- Flour
- Provides the structure that holds the cake together when rolled.
- Sugar
- Sweetens the batter and helps stabilise the whipped egg white frosting.
- Soda
- Reacts with the batter to help it rise and lighten.
- Grated chocolate
- Adds chocolate flavour and colour to one half of the frosting.
The step that matters
Rolling the warm cake. The cake must be rolled while still warm and pliable; once cooled it becomes brittle and is likely to crack. Rolling it before the baked sponge has had time to set in a shape keeps the roll intact.
“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.
