Why it works: Chocolate and cream are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 5,466 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Chocolate Tart
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.
Prepare
Preheat the oven to 350°F (175°C).
Line a pie dish with the puff pastry.
Make and bake the tart
Stir the well-beaten eggs into the prepared chocolate.
Pour the chocolate mixture into the pastry and bake until set.
Top and serve
Stew the apples until tender or use tinned apples.
Place the apples on top of the baked chocolate tart.
Cover with cream and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the chocolate mixture and help it set firm when baked.
- Puff pastry
- Forms a crisp, flaky case that holds the chocolate filling.
- Cooking apples
- Add tart fruitiness and moisture that contrasts with the rich chocolate.
- Prepared chocolate
- Provides the main flavour and the rich, dense body of the filling.
The step that matters
Bake the chocolate filling until set. Eggs set as they heat, so underbaking leaves the filling runny while overbaking can make it dry and grainy. Check that the centre is just firm before removing it.
Swap the apple
How well each one fits the dish's main ingredients (chocolate, egg, cream):
