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 Souffle
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.
Prepare the base
Separate the egg whites from the yolks into different bowls.
Add sugar, flour, and finely grated chocolate to the yolks and stir for 5 minutes.
Make the batter
Whisk the egg whites in the other bowl until stiff.
Gently fold the egg whites into the yolk mixture until smooth.
Butter a round cake tin and pour in the mixture.
Bake and serve
Bake in a moderate oven at 350°F (175°C) for 15 to 20 minutes.
Wrap a white napkin around the tin, sprinkle sifted sugar on top, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air, which lifts the souffle as it bakes and gives it a light structure.
- Egg yolks
- Yolks add richness and fat, and help bind the chocolate into a smooth base.
- Best chocolate
- Melted chocolate adds deep flavour and fat, and gives the souffle its dense, rich body.
- Pounded sugar
- Sugar sweetens the batter and helps stabilise the whipped egg whites.
- Flour
- A small amount of flour gives the base some structure so the souffle holds its shape.
The step that matters
Folding the egg whites into the yolk mixture. Whites hold air only while whisked. Folding gently keeps that air in the batter, so the souffle rises in the oven instead of collapsing.
