Separate 1 egg for the dough. Knead semolina, 150 g flour, egg yolk, whole eggs, approx. 1/2 teaspoon salt, oil and 2-3 teaspoons water first with the dough hooks of the hand mixer, then on a little flour with your hands for approx. 10 minutes.
Form dough into a ball, wrap in foil, let rest at room temperature for about 1 hour. Clean, wash, spin dry and chop the wild garlic finely. Mix with ricotta, season to taste with salt and pepper.
Divide the noodle dough into 3 portions. Roll each portion several times through a pasta machine until the dough is about 1 mm thin. Or roll out on a little flour to 3 equally thin rectangles (each approx. 15x60 cm).
Halve all dough sheets crosswise to make 6 sheets. Put 1 teaspoon of ricotta mixture on each of 3 plates at a distance of approx. 5 cm. Whisk the egg white. Spread the rest of the plates with the mixture, place the filling over the plates and press the spaces between them well.
Between the fillings turn into ravioli of about 6x6 cm or cut with a knife. Bring 3-4 l salted water to the boil in a large pot. For the sauce, bring wine, lemon peel and juice to the boil. Stir in the cream and simmer open for about 10 minutes.
Cook the ravioli in boiling water for 6-8 minutes. Whip the butter in small pieces under the no longer boiling sauce. Season to taste and foam up with a hand blender. Remove the ravioli and serve with the sauce and salad.
