For the Sauce:

Boil the spaghetti in salted water. Drain, cover with cold water, and let stand 15 minutes. Melt the 6 soup spoons of butter in a saucepan, add the drained noodles, stir and put aside.

In a bowl, beat the eggs with half the grated cheese. Add the milk and mix. Pour 2/3 of this sauce over the spaghetti. Mix. Mash the white cheese and mix it into the spaghetti. Pour the noodle mixture into an oven dish. Pour the rest of the sauce over the spaghetti and sprinkle with the remaining grated cheese.

Bake for 30 minutes, until the top turns golden brown.
