We just returned from a few days in Mexico (and picking up my tortilla press in New Jersey en route) and I am mad for homemade tortillas. Where can we buy masa harina cheaply? Several years ago, I would buy it at the Ladbroke Grove Sainsburys which stocked the Cool Chile Co's pricey version. I'd rather buy larger/cheaper quantities. And once I'm making them, I'm sure the dreamy husband will want me to make chilaquiles. Any sources for canned tomatillos?
