Why it works: Vanilla and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓
Chocolate Filling
Ingredients
Directions
Make the filling
Heat 1 cup of milk with a pinch of salt and 1½ squares of ground chocolate in a double boiler until hot and smooth.
Stir in 2 tablespoons of flour moistened in cold milk and cook, stirring constantly, until smooth and thickened.
Continue cooking for 10 minutes, stirring constantly.
In a bowl, mix the yolks of 2 eggs with 5 tablespoons of sugar.
Pour the hot chocolate mixture over the egg mixture, stirring well.
Return the mixture to the double boiler and cook for 2 minutes, stirring constantly.
Cool the mixture, then flavor with vanilla and cinnamon.
Bake and top
Pour the filling into a pie crust and bake for 10 minutes.
Cool again and cover with meringue.

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 becomes the body of the filling.
- Flour
- Thickens the filling as it cooks, giving it a smooth, sliceable set.
- Egg yolks
- Enrich the filling and help it set into a creamy custard as they cook.
- Ground chocolate
- Supplies the chocolate flavour and colour of the filling.
- Sugar
- Sweetens the filling and balances the bitterness of the chocolate.
The step that matters
Return the mixture to the double boiler and cook, stirring constantly. Egg yolks can curdle or scramble if overheated, so gentle heat and constant stirring keep the custard smooth while it thickens.
