The Beef Round Sirloin Tip (Knuckle, Face Rump, Peeled Tip) can be found in most supermarkets and box stores in the meat case, offered as "whole, untrimmed". It is suitable for a variety of cooking methods. Both dry and moist cookery can be utilized to prepare a roast. It's a very lean piece of meat and not suited for a 'low and slow' type cook for beef bbq.
This what it looks like, straight out of the bag (cry-o-vac packing).
This is a 'typical' way of cutting it, but not limited to it alone.
I've taken off a thick "London Broil" and you are looking at the rest
I'll show this "London Broil" in another cooking pictorial
I'm going to remove the rest of the Silver Side, via the natural seam.
The Silver Side can be marinated for Kabobs, lean Stew Meat, lean burger, sandwich steaks, jerky, etc
For my purpses today, I've got a "London Broil" and the rest will be Ground Sirloin.
