Why it works: Chocolate and sugar 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 Tartlets
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cream the egg yolk and sugar together until well combined.
Add the cake crumbs, grated chocolate, cornflour, and melted butter to the mixture.
Whisk the egg white until stiff and gently fold it into the mixture.
Bake and finish
Line 6 patty pans with short-crust pastry and fill them with the mixture.
Bake in a moderate oven at 350°F (175°C) for 20 to 25 minutes.
Once cooled, cover each tartlet with chocolate icing and allow it to harden before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Egg white whisked to stiffness lightens the filling and helps it rise, while the yolk binds it.
- Cake crumbs
- Add bulk and a tender, moist crumb to the filling.
- Grated chocolate
- Provides the chocolate flavour and richness in the filling.
- Cornflour
- Thickens the filling and gives it a softer, more delicate texture.
- Butter
- Adds fat for richness and a smooth, tender texture.
- Castor sugar
- Sweetens the filling and helps the yolk mixture become light when creamed.
The step that matters
Folding in the stiff egg white. Stiff whites hold air that lightens the filling and helps it rise in the oven. Folding gently keeps that air in; stirring vigorously deflates the foam and leaves the tartlets dense.
