Meatball is ground meat rolled into a ball, sometimes along with other ingredients, such as bread crumbs, minced onion, eggs, butter, and seasoning. Meatballs are cooked by frying, baking, steaming, or braising in sauce. There are many types of meatballs using different types of meats and spices. The term is sometimes extended to meatless versions based on vegetables or fish; the latter are also commonly known as fishballs
In an oven preheated to 350 degrees F, these meatballs should be fully cooked through and evenly browned in about 30 minutes. A really good meatball is about 50 percent meat and 50 percent breadcrumbs. The true secret is day-old bread, soaked in milk or water, to bring lightness to the mixture. When you cook beef, pork or veal for too long, it starts to get tougher.Adding a lightly beaten egg, but not too much egg acts as a binder for the ingredients, but you only need a small amount. One small egg will do for one pound of minced meat. Alternatively, if you're following an egg-free diet, you could soak fresh bread in milk, squeezing out any excess milk, to use as a binder
