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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Combine 1 pint of milk with the yolks of 3 eggs in a saucepan.
Prepare the custard as you would for plain boiled custard.
Dissolve the chocolate in a little water.
Once the custard is heated for the second time, stir in the dissolved chocolate quickly.
Allow the custard to come to a hard boil.
Remove the custard from heat and sweeten to taste.
Let the custard cool.
Add vanilla for flavor.
Top and bake
Pour the custard into a dish or bowl.
Beat the egg whites with a little sugar.
Spread the beaten egg whites on top of the custard.
Bake under a lid in a preheated oven at 350°F (175°C) until browned.

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 of the custard and carries the flavor.
- Egg yolks
- Thicken the custard as they set with heat, giving it a smooth, rich body.
- Sweetened chocolate
- Provides the chocolate flavor and sweetness of the custard.
- Egg whites
- Beaten and spread on top, they set and brown in the oven to form a light topping.
The step that matters
Stir in the chocolate quickly after the second heating. Chocolate can clump or turn grainy if it meets hot custard unevenly, so it should be dissolved first and stirred in quickly to blend smoothly.
