She didn't notice all the fat dripping out of 90/10 beef?Sounds excellent. Sure sounds better than just cheese filled, in many Mexican restaurants.
I like the addition of chorizo and your first ingredient LARD.
I keep a tub around all the time.
In fact my wife bought some ground beef that was 90/10.
So before I made the burgers with it, I cut in some lard. Best burgers and wife said "see I told ya".
I said nothing about the lard.......LOL
