The other day I brought home a leftover short rib. I simmered it with some oil, bacon grease and onion. Once recooked I added the usual Mexican spices and shredded it with a fork. I loaded it into a (EDIT) flour tortilla it tasted great, out of this world. My question is there some other stringy beef that you could recommend for tacos in place of short ribs which tend to be expensive? No more hamburger tacos anymore!!!! TIA.
