Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Chocolate Custard
Ingredients
Directions
The book says “a hot oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Scald the milk and stir in the chocolate until dissolved.
Cool slightly.
Beat the egg yolks with the sugar and stir into the milk and chocolate mixture.
Add the vanilla.
Pour into cups.
Place the cups in a baking dish with 1 inch of water around them.
Bake in a 300°F (150°C) oven until set.
Top and serve
Beat the egg whites with the sugar.
Spread on the custard.
Brown in the oven.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that sets into the custard.
- Egg yolks
- Thicken and set the custard as they cook, giving it a rich texture.
- Egg whites
- Beaten into a meringue that browns on top of the custard.
- Sugar
- Sweetens the custard and helps the meringue hold its structure.
- Chocolate
- Provides the main flavour and colour of the custard.
The step that matters
Bake in a water bath until set. Baking the cups in a dish of water keeps the outside gentle so the egg yolks set evenly without curdling or becoming grainy. Overheating causes the custard to weep or turn rough.
