I've never seen prime at Fairway, mostly select. I don't buy beef there for
that reason. I get choice at BJ's If they have prime, I'd grab it, but not
for grinding.

Trimmings. Tiny pieces you'd not want to cook as is.

IMO, 90% lean is way to lean for a juicy burger. I like 80 to 80%. Just add
fat.

I'm not sure aside from the placement in the steer. Placement equates to
tenderness though.
