The higher the percentage on the package means there is less fat in the Ground Beef. There are 3 types of Ground Beef on the market: 70% lean, 80/85% lean, and 93% lean. Before you select your choice of leanness of the Ground Beef, you need to consider what you are going to prepare with it. I like to use the middle 80/85% as my personal preference for Beef Burgers. It provides enough fat to hold the burger together on the grill while also maintaining that moist and juicy taste when cooked. The leanest option, 93%, is great for tacos and other casserole style meals. Look for a product with a bright cherry-red color and firm to the touch. Note though Ground Beef in a vacuum-sealed bag typically has a darker purplish-red color; when exposed to the air, it will turn bright red. Make sure the package is cold with no holes or tears and no excessive liquid. Always purchase it on or before the sell-by date.
