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 Tartlets
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
Rub the chocolate smooth in the milk.
Heat over medium heat and add the cornstarch dissolved in a little more milk.
Stir until thickened, then pour out and let cool.
Once cool, beat in the egg yolks, sugar, vanilla, cinnamon, and salt.
Fill and bake
Fill open tartlet shells with the mixture.
Bake at 350°F (175°C) until set.
In the last few minutes, cover with a meringue made from the egg whites and a little powdered sugar.
Let the meringue color slightly, then remove from the oven.
Serve
Serve cold.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and whites form the meringue topping.
- Baker's chocolate
- Provides the chocolate flavor and color of the filling.
- Cornstarch
- Thickens the milk and chocolate mixture as it heats, giving the custard body.
- Milk
- Forms the liquid base that the chocolate and cornstarch are cooked into.
- White sugar
- Adds sweetness and helps the meringue hold together.
The step that matters
Stir until thickened, then cool. Cornstarch only thickens fully when the mixture is heated and stirred, so it must be stirred until it thickens before cooling. Stopping early leaves a thin filling that will not set properly once baked.
