Chocolate is not just an ingredient; it is an obsession. A mood. A currency of love. This tart is the purest expression of that obsession. It strips away the unnecessary—no heavy cake layers, no distracting fruit fillings—to focus on one thing: the texture of ganache.
A great chocolate tart is a study in contrast. The crust must be short, sandy, and crisp, shattering at the touch of a fork. The filling must be silky, dense, and yielding, coating the tongue before melting away. Achieving this balance requires precision, but the steps are surprisingly simple.
Chapter 1The Chocolate
Since chocolate is the primary flavor, you cannot hide behind sugar. Supermarket baking chips contain stabilizers (soy lecithin) that prevent them from melting into a true emulsion. For this recipe, buy bar chocolate.
Chapter 2The Science of Emulsion (Ganache)
Ganache is an emulsion of fat (cocoa butter + milk fat) in water (from the cream). Just like mayonnaise, if you mix it wrong, it can split, becoming oily and grainy.
The Friction Method: Many recipes tell you to pour hot cream over chocolate. This works, but for a tart, we want a tighter emulsion. We use a spatula to create a "friction core" in the center of the bowl, slowly drawing in liquid until the mixture turns glossy and elastic.
The Crust Secret
We use a pâté sucrée (sweet shortcrust). The secret to a crisp bottom? Blind baking. You must weigh down the crust with beans or pie weights and bake it fully before adding the filling. A raw crust under a wet filling will never crisp up.
The Recipe
Ingredients
For the Crust (Pâte Sucrée)
- 125g Unsalted Butter, room temp
- 85g Powdered Sugar
- 1 Egg, room temp
- 250g All-purpose Flour
- 1/2 tsp Salt
- 30g Almond Flour (optional, for texture)
For the Ganache Filling
- 300g Dark Chocolate (70%), chopped
- 300ml Heavy Cream (35% fat or higher)
- 50g Unsalted Butter, cubed
- 1 tsp Vanilla Extract
- Pinch Flaky Sea Salt (Maldon)
Method
- Make the Dough: Cream butter and powdered sugar until smooth but not aerated. Add the egg and mix. Fold in flour, salt, and almond flour just until combined. Wrap and chill for 1 hour.
- Roll & Line: Roll dough to 3mm thickness. Line a 9-inch loose-bottomed tart tin. Prick the base with a fork. Freeze for 20 minutes (prevents shrinking).
- Blind Bake: Line crust with parchment and fill with pie weights. Bake at 180°C (350°F) for 15 mins. Remove weights. Bake another 10-15 mins until golden brown. Cool completely.
- Make the Ganache: Place chopped chocolate in a heatproof bowl. Bring cream to a gentle simmer (do not boil aggressively). Pour cream over chocolate. Let sit for 1 minute.
- Emulsify: Using a spatula, start stirring in small circles in the center. As it turns dark and glossy, widen your circles. Stir in the butter and vanilla until smooth and shiny.
- Pour & Set: Pour ganache into the cooled shell. Tap gently on the counter to pop bubbles. Let set at room temperature for 2 hours (for a creamy texture) or fridge (for a dense texture).
- Serve: Sprinkle with flaky sea salt just before serving. Slice with a hot, dry knife for clean edges.
Serving Suggestions
This tart is intensely rich. You need something to cut through the density.
- Crème Fraîche: The slight tanginess balances the sugar perfectly.
- Raspberry Coulis: The sharp acidity of raspberries is chocolate's best friend.
- Espresso: Serve with a short shot of black coffee. The bitterness of the coffee highlights the fruit notes in the cacao.
