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 Pie, No. 1
Ingredients
Directions
Make the chocolate base
Dissolve the chocolate in a small amount of milk, then stir it into the boiling water and boil for 3 minutes.
When nearly cold, beat in the yolks of all the eggs and the whites of 3 eggs.
Fill and bake
Stir this mixture into the milk, season, and pour into pie shells lined with puff pastry.
Bake until the custard is set but not more than half done.
Top and finish
Spread the whipped egg whites mixed with 2 tablespoons of sugar over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the custard as it sets, and whipped whites form the light topping.
- Milk
- Provides the liquid base that the custard sets from, giving it a creamy texture.
- Baker's chocolate
- Supplies the chocolate flavour and colour of the custard.
- White sugar
- Sweetens the custard and the meringue-style topping.
The step that matters
Bake until just set. Egg proteins set as they heat, and overbaking squeezes out liquid and makes the custard grainy and watery. Stopping while the centre still trembles lets residual heat finish the set.
