01 - Preheat oven to 350°F.
02 - In a mixing bowl, blend flour, cocoa powder, sugar, and salt. Cut in the cold butter until the texture is coarse and crumbly.
03 - Add egg yolk and 2 tablespoons cold water, mixing until the dough begins to come together. Add an additional tablespoon water if needed.
04 - Shape the dough into a disc, wrap in plastic, and refrigerate for 30 minutes.
05 - Roll the chilled dough on a lightly floured work surface to fit a 9-inch tart pan. Transfer and press evenly into the pan. Trim excess and prick base with a fork.
06 - Line the crust with parchment paper and fill with baking weights or dried beans. Bake for 15 minutes. Remove weights and paper, bake an additional 10–12 minutes until the shell feels firm. Let cool completely.
07 - Heat cream in a saucepan until just below boiling. Pour over chopped chocolate in a bowl, allow to sit for 1 minute, then add butter. Stir until fully smooth and glossy.
08 - Pour the finished ganache into the cooled tart shell. Use a spatula to smooth the surface. Transfer to refrigerator and chill at least 1 hour until set.
09 - Distribute halved strawberries evenly over the set ganache layer.
10 - Warm apricot jam and lightly brush over strawberries for a glossy finish.
11 - Portion into slices and serve chilled or at room temperature.
