LEMON TART RECIPE - LEMON CROSTATA FROM THE RIVER CAFE COOKBOOK

Steps:

• For the sweet pastry, pulse the flour and butter with a pinch of salt in a food processor, until the mixture resembles coarse breadcrumbs. Add the icing sugar, followed by 3 of the egg yolks and pulse. The mixture will immediately combine and leave the sides of the bowl. Remove the pastry, wrap in cling film and chill in the fridge for at least 1 hour.
• Heat the oven to 160°C/fan oven 140°C/mark 3. Coarsely grate half the pastry into a 30cm loose-bottomed fluted flan tin, then press it evenly onto the sides and base. Chill in the fridge for 15 minutes. Freeze the remaining pastry.
• Line the pastry case with greaseproof paper and fill with uncooked rice (or dried beans or baking beans). Bake blind for 20 minutes. Remove the paper and rice, then bake for a further 10 minutes, or until golden brown. Leave to cool.
• Meanwhile, make the filling. Put all the remaining ingredients, except the softened butter, in a large saucepan over a very low heat and whisk until the eggs have broken up and the sugar has dissolved.
• Add 150g of the butter and continue to whisk. At this point, the eggs will start to cook and the mixture will thicken enough to coat the back of a spoon. Add the remaining butter and continue whisking until the mixture becomes very thick. It is important to keep whisking throughout the cooking process to prevent the mixture from curdling.
• Remove the saucepan from the heat and set it on a cold heatproof surface. Continue to whisk until the mixture is lukewarm. Meanwhile, preheat your grill to full heat.
• Spoon the lemon filling into the pastry case and leave to settle for 5 minutes. Grill until the top of the crostata is mottled brown - this should take 3-5 minutes. Allow to cool before serving.

CLASSIC LEMON TART

Steps:

• Make the crust: In a small saucepan over medium heat, melt the butter. (If you like, you can let the butter cook until it browns and smells nutty, 2 to 4 minutes longer.)
• Whisk together flour, confectioners' sugar and salt in a medium bowl. Drizzle in melted butter and, using a spatula, mix until well combined. Press this into the bottom and up the sides of a 9-inch tart pan, using a measuring cup if you like to flatten the tart shell and make sure it's even. Place in the freezer for at least 30 minutes and up to 2 months (wrap in plastic if storing for more than 4 hours).
• Heat oven to 350 degrees. Line tart dough with a piece of foil or parchment paper and fill with pie weights, dry beans or rice. Bake for 15 minutes, then remove the foil and weights and continue to bake until the crust is very lightly golden at the edges and baked through on the bottom, 10 to 15 minutes longer. Transfer to a rack to cool. (Tart shell can be made up to 1 day ahead and kept at room temperature.)
• Make the curd: Put butter, lemon zest, lemon juice and sugar in a heavy saucepan over medium heat. Cook until butter is melted and mixture is hot, 4 to 5 minutes.
• In a medium bowl, beat together eggs, yolks and salt. Whisk the hot mixture gradually into the eggs to temper them. Then pour everything back into the saucepan and return to medium-low heat. Cook, whisking constantly, until mixture thickens enough to coat the back of a wooden spoon (170 degrees; do not overcook, or it will curdle), about 5 minutes. Pour through a fine-meshed sieve into a bowl. Taste and add a bit more sugar if you like. It should taste tart but balanced.
• Spread the curd (it's OK if it's still warm) into the tart shell, spreading it evenly with a small offset spatula or butter knife. Return to the oven to bake until the curd is just set along the edges but still jiggly in the center, about 7 to 15 minutes. (It will continue to firm up as it cools.) Transfer back to the wire rack to cool completely, at least 2 hours, before serving. If the curd still looks a little loose after cooling, you can chill the tart for an hour or two before serving. Note that it's a soft curd but shouldn't be runny.

SUMMER BERRY CROSTATA WITH LEMON CURD

Steps:

• Place oven rack in lowest position, and heat oven to 450 degrees. Place large pizza stone on rack, and heat 1 hour while preparing other ingredients. Cut 6 sheets of aluminum foil, each one 8 inches square, and set aside.
• Make the crust: Combine flours, sugar and salt in food processor, and pulse to combine. Remove lid, scatter butter over surface of flour and pulse until butter pieces are no longer visible, 10 pulses of 10 seconds or so each. Turn mixture into mixing bowl, and sprinkle with 4 tablespoons ice water. Toss lightly with fingertips. Gather dough together, and squeeze a small portion with fingers. If dough feels dry, add another tablespoon water, and toss to combine. Turn dough onto work surface, press together firmly and pat into round disk. Cut into 6 wedges. Roll each wedge into a ball, flatten slightly and wrap in plastic wrap. Refrigerate at least 30 minutes, and up to 24 hours.
• Make the curd: Place small, conical stainless-steel strainer over 2-cup glass measuring cup, and set aside. In small, heavy nonreactive saucepan, whisk egg, yolks and sugar together. Add lemon juice, and whisk to combine. Add zest, butter and salt. Place pan over medium heat, and cook, stirring constantly with wooden spoon, until mixture is shiny, opaque and thick enough to coat back of spoon, about 5 minutes. Do not boil. Remove from heat, and stir in cream. Strain immediately into glass measuring cup, cover and refrigerate until ready to use.
• Make the blueberry filling: Place half the blueberries in medium saucepan. Add cornstarch and sugar, and stir well. Add lemon juice and salt. Cook over medium heat, stirring constantly, until blueberries give up juices, thicken and simmer a bit. Compote will be very thick. Remove from heat, and stir in remaining blueberries. Cool.
• Assemble the crostata: Working 1 piece of dough at a time, flour top and bottom lightly, and roll into thin 8-inch round. Transfer round to a square of foil. Spoon 1 1/2 to 2 tablespoons of desired filling in center, leaving 2-inch periphery free. Mound fruit in a circle. (Be sure to use all the filling in the 6 crostatas.) Fold dough over to support filling. Place crostata on sheet pan in refrigerator, and continue forming tarts with remaining dough pieces and fruit filling. Refrigerate all 6 crostatas at least 20 minutes.
• Slide 2 or 3 crostatas onto baking stone. Bake until dough is dark golden brown, 15 to 20 minutes. Remove, and cool 10 minutes on rack. Repeat with remaining crostatas. Sprinkle with confectioners' sugar, or add a dollop of whipped cream or a few tablespoons of chilled heavy cream. Serve.

LEMON CROSTATA

Steps:

• Pulse almonds with 1/4 cup flour in a food processor until finely ground, being careful not to grind to a paste.
• Beat together butter and sugar with an electric mixer until pale and fluffy. Chill 1 tablespoon beaten egg for egg wash and beat remaining egg into butter mixture. Beat in vanilla and almond extracts. At low speed, mix in almond mixture, zest, salt, and remaining 1 3/4 cups flour until a dough just forms. Halve dough and form each half into a 5- to 6-inch disk. Wrap disks separately in plastic wrap and chill until firm, at least 30 minutes.
• Beat yolks with 3/4 cup sugar using cleaned beaters until very thick and tripled in volume, about 5 minutes. Transfer to a heavy medium saucepan and stir in zest, juice, butter, and salt. Cook over medium-low heat, whisking frequently, until curd is thick enough to hold marks of whisk and mixture begins to bubble, about 6 minutes. Transfer lemon curd to a bowl and chill, its surface covered with parchment paper, until cold, at least 1 hour.
• Preheat oven to 375°F with rack in middle. Generously butter springform pan.
• Roll out 1 piece of dough (keep other piece chilled) between 2 sheets of parchment into a 12-inch round (dough will be very tender). Remove top sheet of parchment and invert dough into springform pan. (Dough will tear easily; patch it with your fingers.) Press dough over bottom and 1 inch up side of pan, trimming excess.
• Chill shell and roll out remaining dough between sheets of parchment into a 12-inch round. Remove top sheet of parchment, then cut dough into 10 (1/3-inch-wide) strips with pastry wheel and slide, still on parchment, onto a baking sheet. Chill until firm, 30 to 45 minutes.
• Bake shell until bottom is pale golden and edge is golden, 15 to 20 minutes. Cool shell in pan on a rack, about 30 minutes.
• Spread filling in shell and arrange 5 strips 1 inch apart on filling. Arrange remaining 5 strips 1 inch apart diagonally across first strips to form a lattice with diamond-shaped spaces. Trim edges of all strips flush with edge of shell. Brush lattice top with egg wash and sprinkle crostata with remaining tablespoon sugar.
• Bake crostata until pastry is golden and filling is bubbling, 25 to 30 minutes. Cool completely in pan on a rack, about 2 hours (juices will thicken).
