Wash and clean the zucchini, grate roughly and mix with 1/2 teaspoon salt. Coarsely grate cheese
For the dough mix flour and 1 teaspoon salt. Add 160 g butter, 50 g Gouda and 6 tbsp water and knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Halve the dough, wrap in foil and chill
Wash lemon hot, grate dry, grate peel thinly. Halve the fruit and squeeze the juice. For the filling, pour the zucchini into a sieve and squeeze the vegetable juice. Heat 2 tablespoons of butter and olive oil in a saucepan. Clean and wash spring onion and cut into fine rings. Peel garlic and chop finely. Fry in hot fat for about 4 minutes until translucent. After about 3 minutes add the zucchini. Season with 2 tsp lemon juice and pepper

Divide both pieces of dough into thirds and roll out round (10-12 cm Ø) on a floured work surface. Spread the filling over the circles, leaving about 2 cm free to the edge. Toss up any excess dough and carefully spread the dough pieces on a baking tray lined with baking paper. Sprinkle with remaining cheese. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 20-30 minutes. Let the dough pieces cool slightly and sprinkle with the remaining basil.
