El Porvenir Tortilla Factory isn't much to look at — from either the outside or inside. But don't let the dusty shelves in the dimly lit store turn you off, because this family business has been churning out the best flour and corn tortillas in Arizona since 1954. Delivered daily to stores across the state, you’ve probably seen the packages, stamped with a red eagle, at your local grocer. If you want to cut out the middle man, however, go directly to the Tortilla Factory for a package of warm, preservative-free tortillas that are the next best thing to homemade. Red Eagle has a variety of sizes to accommodate everything from soft tacos to good-size burritos. Unlike most tortillas, you’ve got to keep these flavorful treats in the refrigerator (or eat ’em fast) because they don’t contain the preservatives that give their competitors’ products a longer shelf life — and a rubbery texture.
