Check the 1lb, 5lb or 10lb "tubes" of pre-measured hamburger meat. That's where I usually find the 70/30 stuff.
I think I bought a tube of hamburger once. It was gross. Never did that again.
Wal-Mart has hamburger patties made of beef hearts. Ultimate gross-out! Arteries!
If it was 70/30, I didn’t notice. But it probably was.
I know for sure I’ve never seen 70/30 on the packages they make right in the store. 80/20 is the fattiest I’ve seen.
