The active muscles, such as the legs and thighs, are full of blood vessels. These blood vessels contain myoglobin (or muscle hemoglobin), which delivers oxygen to the muscles. The more myoglobin the muscles contain, the darker the muscle. Scientists often refer to these active muscles as slow-twitch fibers.
Background. Beef jerky is a type of snack food that is made by marinating beef in a curing solution and drying it. Meat treated in this way has a long shelf life and a unique flavor. Invention of this meat processing technology is attributed to Native Americans who smoke-dried meat to preserve it.
I found jerky making in the oven to be very easy and pretty fast. When your meat is semi frozen slice it as thin as you can with a knife or about an eigth inch on a slicer. Dump it into a container and dose with soy sauce, garlic salt, and hot suace. Just guess at what will taste good for the first batch. This is so easy that you will make it again and adjust the recipe.
