Basically "Bortz/Mongolian Dried Beef" is a simple method of making air dried beef /beef jerky. I would suggest you take a look at the seasoning(s) you want to use and make a simple jerky. As noted below, the meat is cooked with a sauce, like the restaurant version of Mongolian Beef/BBQ etc.I have been online seeing references to Mongolian dried beef. I am unable to find a recipe. Anyone have any thoughts?
