Spaghetti alla Carbonara

First, cook spaghetti according to the instruction on the bag.

While spaghetti is cooking, put cooking oil to the saucepan and warm on medium heat. Cut the ham into small pieces. At this time, separate egg yolks and egg whites. (You can use egg whites to make meringue cookies later). Add ham to the oil, stir and let it fry for about one minute. Add sour cream, stir thoroughly. When sour cream is heated up, add egg yolks one by one stirring constantly. Cook this sauce for another few minutes, keep stirring until it starts thickening. Add seasonings (salt, paper, oregano) to your taste.
