Rub the butter into the flour; add the ground almonds and the icing sugar, followed by the egg and the salt. Mix until you have a consistent pastry without overworking it. Leave it to rest in the fridge for 12 hours.
beat the softened butter into the sugar and ground almonds. Mix in the eggs and cornflour without creating a mousse.

Using a rolling pin, roll out the sweet shortcrust pastry to a thickness of approximately 2 to 3 mm. Line a 22 cm diameter, 2 cm high flan ring. Criss-cross the pastry with a small knife so that the bottom of the tart doesn’t rise up during cooking.
Preheat the oven to 170°C (338°F) and precook for 10 minutes. Fill the bottom of the tart with the almond cream and place 200 g of raspberries on top. Cook for 35 minutes. The pastry should be well-cooked and the almond cream should stay soft and moist. Leave the tart to cool on a rack.
Soak the almond cream with the raspberry pulp and let it sink in. Using a piping bag and a Saint Honoré piping nozzle, fill the tart with the lime and basil mascarpone cream. Finally, sprinkle with the lime zest, arrange the rest of the raspberries on top and decorate with the julienne slices of confit lime.
Serve at a temperature of approximately 12°C (53.6°F) with a rosé champagne.
