Meat grinders
This is something that hasn’t changed very much since it came out in the early-1900s. Hand-crank meat grinders are a simple product that slices and minces meats to a fine, even consistency, letting you make classic dishes like burgers, hamburger helper, and meatloaf. You can even still get your hands on a hand-operated meat grinder at your local restaurant supplies store.
But if you want to make life and save your wrists from weeks of aching, then you should get a meat-grinder attachment for your KitchenAid stand mixer. Or you can get a dedicated electric meat grinder if you’re really into it.
