Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Cakes
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 butter and sugar together until creamy.
Add the beaten eggs and flour alternately, then mix in the vanilla.
Pour the batter into a well-buttered deep jelly cake tin.
Bake for 20 minutes, then turn out and allow to cool.
Glaze and finish
Cut the cooled cake into small rounds or diamonds.
In a saucepan, combine icing sugar, grated chocolate, caramel, and water.
Stir over low heat until the mixture is liquid.
Dip the cakes into the chocolate mixture and place on a board to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Provide structure and help the batter rise and set as it bakes.
- Flour
- Forms the structure of the cake as its proteins set in the oven.
- Sugar
- Sweetens the cake and helps create a light, creamy batter when beaten with butter.
- Grated chocolate
- Gives the glaze its chocolate flavour and rich, dark colour.
The step that matters
Stir the glaze over low heat until liquid. Icing sugar and chocolate can scorch or seize if overheated, leaving a grainy or burnt coating. Gentle heat melts the chocolate and dissolves the sugar into a smooth, pourable glaze.
