Outstanding corn tortillas -- blue, yellow, and white -- made from stone-ground corn masa and 100% fresh nixtamal. Available at their stand at the Saturday morning Portland Farmers Market at PSU as well as the People's Food Co-op, New Seasons, and Whole Foods.
A local company, Three Sisters makes what those who know say are the best organic tortillas in the Pacific NW since they're the only tortilla retailer in the area that uses organic nixtamalized corn. You can taste the difference. Even if you haven't picked up a pack of their actual tortillas at the farmers market or an area store you've probably eaten them at one of the better, higher-end Portland restaurants that serve tortillas.
It's always great to come across and support yet another local company that uses traditional methods and organic, non-GMO materials to produce a tasty, high-quality product.
