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 Tarts
Ingredients
Directions
Make the filling
Rub the chocolate smooth in the milk and heat to boiling.
Stir in the corn-starch and cook for five minutes until thickened.
Remove from heat and pour into a bowl to cool.
Combine and bake
Beat the yolks and whites of two eggs with the sugar.
When the chocolate mixture is almost cold, combine with the egg mixture and vanilla, stirring until light.
Bake in tartlet shells until done.
Top and serve
Top with meringue made from the whites of two eggs and two tablespoons of sugar, flavored with lemon juice.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and thicken the filling, while whites whip into the meringue topping.
- Chocolate
- Provides the chocolate flavor and body of the filling.
- Corn-starch
- Thickens the chocolate mixture as it cooks.
- Milk
- Forms the liquid base that the chocolate melts into.
- Sugar
- Sweetens the filling and helps stabilize the meringue.
The step that matters
Combining the cooled chocolate with the egg mixture. If the chocolate is still hot, it can cook the egg yolks and make the filling grainy or curdled. Waiting until it is almost cold keeps the eggs smooth and the filling light.
