The guy at the meat shop tipped me off. So I walked down 22nd Street past the Chase bank and the flower store with the cartoon leprechaun until I came to a little truck parked in a huge dirt lot. Taqueria y Raspados Jason looks to be the local spot for Sinaloa-style macedonia ice cream treats, burros and corn masa sopes.   

But I am writing about the lengua today, because it's outstanding. Big chunks of beef tongue that get soft-boiled for three hours with garlic, onion and Anaheim chiles. Then they get chopped up into big, springy chunks that plop around on your tongue. Pick one up in your hand, and it easily shreds into strings of juicy meat. Weird, huh?     

Insider's tip: It's freaking hot out there! So duck into Evergreen Flowers next door and chill out for a minute in their walk-in cooler ... 

Location: I caught up with the truck at 6041 E. 22nd St. But the folks behind Taqueria Jason also have two Jason's Mexican Food restaurants at 2400 N. Pantano Road and 4230 N. Oracle Road, Suite 100.
