I ran into the chef of Maria y Ricardos Tortillas yesterday and he introduced me to a new product of theirs: soft corn tortillas. They're deep yellow and redolent of corn. And they're very soft. I plan to use them for my kids' lunches since the tacos will stay soft all day and have a nice toasty flavor right out of the bag. He said they're at Whole Foods, but I didn't see them in Woburn earlier this week.
