Geometric Rhubarb Tart Recipes

Steps:

• Preheat oven to 400°. Unfold 1 pastry sheet and place on a parchment-lined baking sheet; repeat with remaining pastry sheet. Whisk egg and water; brush over pastries. Using a sharp knife, score a 1-in. border around edges of pastry sheets (do not cut through). With a fork, prick center of pastries. Bake until golden brown, about 15 minutes. With a spatula, press down center portion of pastries, leaving outer edges intact. Remove to wire racks to cool., Meanwhile, for topping, arrange rhubarb in a single layer in a 13x9-in. baking dish. Combine orange juice, honey and amaretto; pour over rhubarb. Bake at 400° until rhubarb is just tender but still holds its shape, about 10 minutes. Remove with a slotted spoon, reserving cooking liquid; let rhubarb cool. Transfer reserved cooking liquid to a small saucepan; bring to a boil over medium-high heat. Reduce heat; simmer until reduced to 1/2 cup, about 20 minutes. Cool., For filling, stir together mascarpone cheese, amaretto and honey until smooth. Spread mascarpone mixture over center of each pastry. Top with rhubarb ribs. Brush rhubarb with cooled cooking liquid. Refrigerate leftovers.

Steps:

• Heat oven to 220C/fan 200C/gas 7. Roll the pastry out thinly and, using a plate or cutter, cut out 4 circles about 14cm in diameter. Use a slightly smaller cutter to cut a circle out of the middle and trim away the outside border, reserving these trimmings.
• Lay the 4 circles on a baking sheet, prick all over with a fork and brush the edges with egg. Use the pastry trimmings to make a border around the edge like a vol-au-vent and press down gently with your thumb. Chill until needed. This can be done up to 1 day ahead or frozen for up to 1 month.
• In a small bowl, mix the demerara sugar with the crème fraîche and spread a thin amount over the base of each tart. Neatly arrange slices of rhubarb, overlapping in a floral pattern, over the crème fraîche, then dust generously with icing sugar. Bake the tarts for 20 mins until puffed up and golden. Leave to rest for a few mins and eat warm with a scoop of ice cream, if you like.
