Eliminate the woody parts of the asparagus spears then blanch them for a few minutes with the peas. Set to one side. Mix the ricotta, Gorgonzola PDO, two eggs, cream, chopped basil and mint together in a bowl. Whisk and add salt and pepper to taste.
Add 3/4 of the peas and the asparagus cut into rounds. Set the tips to one side. Grease a baking tray with oil and roll out the roll of pastry.
Prick the pastry with a fork, pour in the mixture and level the surface. Add the asparagus tips and peas.
Brush the edges of the pastry with the beaten egg yolk and bake in a preheated oven at 200°C for 30 minutes. Leave to cool and garnish with lemon zest and a few mint leaves.
