Although this dish calls for many ingredients, they are all readily available and the dish is easv to make; yet somehow, it seems elaborate. In the time of the monzu' chefs. it was called gatto di patate, from gateau or cake in French. Normally we eat it hot, then have the leftovers -if any- cold the next day. It tastes even better!
