This recipe comes from Urbain Dubois & Emile Bernard, "La Cuisine classique", 1864. Yes 1864. The flavor is great, and placing the parmesan cheese into the eggs separates the cheese flavors. Preparation time includes grating the cheese and mixing the eggs. Cooking times very to taste. Some like eggs well done, I prefer them just set. This I leave up to you to decide. This recipe yields 2 servings.
