Yeah, they must be long-cooked to soften. But, if you have good choppers, they have that wonderful beefy flavor that more expensive cuts lack. As an American, I want it all.
That is exactly the way to have ground beef.
When you hear news stories of people sickened by commercial ground beef, the danger is self apparent. Meat with bacteria on the outside is ground up and the pathogens spread throughout.
I never buy factory burger.
Now if you buy the cheap steaks or roasts, then you can chop it yourself and be confident that it’s safe.
Probably a good vinegar scrub and rinse with water would not be a bad idea.
Cut it into chunks and put it in the food processor. You can control the fat content that way as well.
