"Hamburger Rocks" are small chunks of cooked, dehydrated, fresh beef. They will store effectively for two or more years. Once rehydrated by soaking one cup of rocks in two cups of boiled water, the pre-cooked meat can be used in any recipe. It is delicious for tacos, spaghetti sauce, hamburger helper, tamale pie, lasagna, or your favorite recipe. It is very difficult to distinguish from fresh hamburger in a meal!
