For the croxetti, mix all the ingredients until a homogeneous mixture is obtained. Roll out the thin dough with a rolling pin and, with the special mold, make the croxetti.
For the walnut sauce, use a mortar to grind the walnuts with the garlic and marjoram.
Put the bread to soak in the milk, squeeze it well and add it to the walnuts in the mortar. Mix everything well and finally add the grated cheese and extra virgin olive oil.
Cook the croxetti in abundant salted water. Dilute the walnut sauce with a tablespoon of cooking water. Drain the croxetti and toss with the walnut sauce.
