Ingredients:
- 1 1/4 cups (150g) all-purpose flour, plus extra for dusting
- 1/4 cup (25g) unsweetened cocoa powder
- 1/4 cup (50g) granulated sugar
- 1/4 teaspoon salt
- 1/2 cup (113g) unsalted butter, cold and cubed
- 1 large egg yolk
- 2-4 tablespoons ice water
- 1 pound (454g) fresh strawberries, hulled and roughly chopped
- 1/2 cup (100g) granulated sugar
- 2 tablespoons lemon juice
- 1 teaspoon gelatin powder
- 2 tablespoons cold water
- 1 cup (237ml) heavy cream, cold
- 1/2 pound (227g) fresh strawberries, hulled and sliced into heart shapes
Instructions:
- Combine flour, cocoa powder, sugar, and salt in a food processor. Pulse to combine.
- Add cold butter and pulse until the mixture resembles coarse crumbs.
- Add egg yolk and ice water, one tablespoon at a time, until the dough just comes together.
- Form dough into a disc, wrap in plastic wrap, and chill for at least 30 minutes.
- Roll out dough on a lightly floured surface and cut into circles slightly larger than the tartlet tins.
- Press dough into the tartlet tins, trim edges, and prick the bottoms with a fork.
- Chill for another 15 minutes.
- Line the tart shells with parchment paper and fill with pie weights.
- Bake at 375°F (190°C) for 15 minutes. Remove weights and parchment paper and bake for another 5 minutes, or until the crusts are firm.
- Let cool completely in the tins.
- Puree strawberries, sugar, and lemon juice in a food processor until smooth.
- Strain the mixture through a fine-mesh sieve to remove seeds.
- In a small bowl, sprinkle gelatin over cold water and let stand for 5 minutes to bloom.
- Heat a small portion of the strawberry puree in a saucepan until warm but not boiling.
- Remove from heat and stir in the bloomed gelatin until dissolved.
- Combine the gelatin mixture with the remaining strawberry puree.
- In a stand mixer (or with a hand mixer), whip heavy cream until stiff peaks form.
- Gently fold the whipped cream into the strawberry puree until just combined.
- Pour the mousse into the cooled tart shells and chill for at least 2 hours, or until set.
- Carefully remove the tartlets from the tins.
- Arrange heart-shaped strawberry slices on top of the mousse.
- Serve immediately or chill until ready to serve.
