An interesting and different recipe from an old cookbook from the 50s. The recipe calls for basilica. I have no idea what that is but I use sweet basil because other places in the book basil is suggested as a substitute. It's not a real "ravioli" as there is no pasta pockets, thus much easier to make.
Mix together the spinach, Ricotta and Parmesan cheeses, salt and pepper, and the egg
Shape the mixture into balls about the size of large marbles and roll them in flour
Drop the balls into boiling water for 20 minutes, then remove with a slotted spoon to a serving dish.
Pour the sauce over the Ricotta balls and top with additional Parmesan cheese.
To make the sauce, fry the garlic and onion in oil until golden. Add celery to the meat and cook, stirring often, until meat is brown. Add remaining ingredients, cover, and simmer slowly for,2 hours. Pour hot over the Ricotta balls.
