Chocolate Espresso Tart Recipes

Steps:

• Make the ganache: Put chocolate into a medium heatproof bowl, and set aside. Bring cream and espresso to a boil in a small pan. Pour through a fine sieve over the chocolate; discard solids. Let stand 2 minutes, then whisk until smooth. Let cool to room temperature, 1 to 2 hours.
• Make the tart shell: Sift flour, salt, and cocoa powder into a medium bowl; set aside. Put butter and sugar into the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until pale and fluffy, about 4 minutes. Add egg and vanilla, and mix until combined, scraping down sides of bowl as needed. Reduce speed to low. Gradually add the flour mixture in 3 batches, alternating with the cream. Shape dough into a thick rectangle; wrap in plastic. Refrigerate until cold, about 30 minutes.
• Preheat oven to 350 degrees. Roll out dough between 2 pieces of lightly floured parchment paper to a 16-by-6-inch rectangle, about 1/4 inch thick. Press dough into a 14-by-4 1/2-inch rectangular flan frame set on a baking sheet lined with parchment. Trim dough flush with top edge. Prick all over bottom of shell with a fork. Bake until firm, 18 to 20 minutes. Transfer to a wire rack; let cool completely. Unmold.
• Put ganache into the bowl of an electric mixer fitted with the whisk attachment; beat on medium-high speed until soft peaks form, about 4 minutes. Transfer to a pastry bag fitted with a large star tip (such as Ateco No. 828).
• Smooth mascarpone cheese over bottom of tart shell with an offset spatula.
• Pipe ganache rosettes, one next to the other, on top of mascarpone to cover.

Steps:

• To make the pastry: combine the flour, sugar, and salt in a large mixing bowl. Add the butter and mix with a pastry blender or hands until the mixture resembles coarse crumbs. Make a well in the middle of the pastry. Combine the egg yolk with the ice water in a small bowl, whisking to blend; pour it into the well and work it in to bind the dough until it holds together without being too wet or sticky. Squeeze a small amount together, if it is crumbly, add more ice water, 1 tablespoon at a time. Form the dough into a disk and wrap in plastic; refrigerate for at least 30 minutes.
• Roll out the pastry on a lightly floured surface into a 12-inch circle, about 1/4-inch thick. Carefully roll the dough up onto the pin (this may take a little practice) and lay it inside a 9-inch tart pan with a removable bottom. Press the dough into the pan so it fits tightly; press the edges into the sides of the pan. It is important to press the dough evenly into every nook and corner of the ring, especially the scalloped edges. Shave off the excess hanging dough with a knife. Put the tart in the refrigerator for 15 minutes to relax.
• Preheat the oven to 350 degrees F.
• Place the tart pan on a sturdy cookie sheet so it will be easy to move in and out of the oven. Line the tart with aluminum foil and add pie weights or dried beans to keep the sides of the tart from buckling. Bake for 30 minutes, then remove the foil and weights. Using a pastry brush, lightly coat the crust with a beaten egg white. Return to the oven and continue to bake for another 8 minutes until the tart is golden in color, but not brown. Remember the tart will be cooked again with the filling. It should be cooked but light in color so that it will not burn on the second bake. Set aside to cool and lower the oven temperature to 325 degrees F.
• To make the filling: Heat the heavy cream and milk in a pot over medium-low flame, until it simmers slightly around the edges. Remove from the heat; add the chopped chocolate and stir until melted and smoothed out. Add the sugar and salt and whisk until well incorporated. Beat the eggs in a small bowl until blended and add them to the chocolate mixture, stir until completely blended. Pour the filling into the cooled tart shell and bake at 325 degrees F for 15 to 20 minutes until the filling is set and the surface is glossy. If you see any bubbles or cracks forming on the surface, take the tart out right away - that means it is beginning to become over baked. Cool before cutting.

Steps:

• Preheat oven to 350°F Butter an 8-inch cake pan (I used a springform pan) and line bottom with parchment paper. Butter the parchment and lightly flour (or use cocoa) the pan, shaking out excess.
• In a small, heavy-based saucepan, melt chocolate and butter over medium heat, stirring frequently. Set aside.
• Using the whisk attachment of a stand mixer, whip the eggs, sugar, brewed espresso, ground espresso beans, and salt on medium-high speed until thick and voluminous, at least 8 minutes (I mixed about 10 minutes). Turn the mixer to low and mix in the chocolate-butter mixture. Turn off mixer and sift the flour over the batter and fold until all the ingredients are fully incorporated.
• Pour batter into prepared pan and bake until a skewer inserted in the center comes out clean, 25-30 minutes.
• Cool in the pan on a rack for 10 minutes. Set a plate over the torte and carefully invert the torte onto the plate; peel off the parchment. Flip the torte back onto the rack to cool completely before slicing. (Since I used a springform pan, I let it cool completely in the pan.).

Steps:

• For the base: Snap the oreos into pieces and drop them into the bowl of a food processor. Do likewise with the chocolate, then blitz them together until you have crumbs. Add the butter and salt, and blitz again until the mixture starts to clump together. If you're doing this by hand, bash the cookies in a freezer bag until they form crumbs, finely chop the chocolate and melt the butter, then mix everything, along with the salt, in a large bowl with a wooden spoon or your hands encased in disposable gloves.
• Press the mixture into a 23-centimeter/10-inch deep-sided, loose-bottomed flan or tart pan. Pat down on the bottom and up the sides of the pan with your hands or the back of a spoon, so that the base and sides are evenly lined and smooth. Put into the fridge to chill and harden for at least 1 hour, or 2 hours if your fridge is stacked. I wouldn't keep it for longer than a day like this as the Oreo crust tends to get too crumbly.
• For the filling: Finely chop the chocolate. Put the corn starch into a cup and whisk in the milk until smooth. Pour the cream into a heavy-based saucepan into which all the ingredients can fit and be stirred without splashing out of the pan, then add the finely chopped rubble of chocolate, the sieved cocoa (or just sieve it straight in), espresso or instant coffee powder, sugar, vanilla paste or extract, olive oil and smoked salt. Place over a medium to low heat and whisk gently--I use a very small whisk for this, as I'm not aiming to get air in the mixture, I'm just trying to banish any lumpiness--as the cream heats and the chocolate starts melting.
• Off the heat, whisk in the corn starch and milk mixture until it, too, is smoothly incorporated, and put the pan back on a low heat. With a wooden spoon, keep stirring until the mixture thickens, which it will do around the 10-minute mark, but be prepared for it to take a few minutes more or less. Take the pan off the heat every so often, still stirring, so that everything melds together, without the cream coming to a boil. When ready, it should be thick enough to coat the back of a wooden spoon, and if you run your finger through it (across the back of the spoon) the line should stay.
• Pour the mixture into a wide measuring jug or batter jug (it should come to about the 600 milliliter/2 1/2 cup mark). Now run a piece of baking parchment or greaseproof paper under cold water, wring it out and place the damp, crumpled piece right on top of the chocolate mixture, then put the jug into the fridge for 15 minutes. The mixture will still be warm, but will be the right temperature to ooze into the base without melting it.
• Pour and scrape the mixture into the cookie-lined tart pan and put it back in the fridge overnight. Don't leave it longer than 24 hours, as the base will start to soften.
• Take the tart out of the fridge for 10 minutes before serving, but unmould straight away. Sit the tart pan on top of a large tin or jar and let the ring part fall away, then transfer the dramatically revealed tart to a plate or board. Leave the pan base on.
• Slice modestly--this is rich and sweet, and people can always come back for more--and serve with creme fraiche; the sharpness is just right here. Leftovers will keep in the fridge for 4 to 5 days, but the base will soften and the sides crumble a bit. That will not detract from your eating pleasure too much, but I still like to give it its first outing at optimal stage!
