I've felt this way ever since I was a kid. I love eating ground beef, whether hamburgers, meatloaf, or spaghetti sauce, but I dislike eating steak of any kind. Both are beef, but I enjoy eating ground beef more because I like the texture and flavor better. Maybe it's because the fibres are already broken up in the grinding process so I don't have to do as much work chewing.
In any case, I've always felt my preference for ground beef might be unusual because steak is considered to be somehow superior to hamburger.
Does anyone else feel like I do?
