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 Puffs
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Beat the egg whites until stiff.
Gradually beat in the powdered sugar.
Finely grate the chocolate and dredge it with flour to prevent oiling.
Mix the dredged chocolate with the egg and sugar mixture, stirring well.
Shape the puffs
Line a square tin pan with white paper.
Place spots of powdered sugar about the size of a half dollar on the paper.
Put a portion of the mixture on each spot, smoothing it with a knife dipped in cold water.
Sift white sugar over the top of each puff.
Bake and serve
Bake in a brisk oven at 400°F (200°C) for a few minutes.
Once cooled, loosen the puffs with a broad knife.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam, they give the puffs their light, airy structure.
- Powdered sugar
- Sweetens the mixture and dissolves into the whipped whites, helping stabilise the foam.
- Chocolate
- Provides the main chocolate flavour and the solid body of each puff.
- Flour
- Lightly coats the grated chocolate so it disperses evenly instead of releasing oil.
The step that matters
Dredging the chocolate with flour. Grated chocolate left bare can release its cocoa butter as oil when mixed in, which makes the mixture greasy and weakens the foam. A light flour coating keeps the chocolate evenly dispersed.
