While three−quarters of a pound of macaroni are boiling in salted water prepare the following: Chop up fine two ounces of ham fat with a little parsley. Peel six medium−sized tomatoes, cut them open, remove the seeds, and any hard or unripe parts, and put them on one side. Take a frying−pan and put into it one scant tablespoon of butter and the chopped ham fat. When the grease is colored put in the sliced tomatoes with salt and pepper. When the tomatoes are cooked and begin to sputter put the macaroni into the pan with them, mix well, add grated Parmesan cheese, and serve.
