The Lea and Perrins Brand of Worcestershire Sauce has been around since the early 1800’s enhancing many foods and drinks; except it is not Gluten Free. “The Wizard’s” Organic Gluten Free Vegan Worcestershire Sauce, manufactured by Edward’s and Sons Trading Company is the is sold at Planet Organic and is available on-line. Recently, we found "French's" Brand Gluten Free Worcestershire Sauce at Superstore. Here is a favorite marinade for flank steak that we haven’t had in a long long time. The flavor of the Worcestershire Sauce really comes through. Flank steak is really lean and must be marinated for at least 8 hours, overnight is best. We don’t count carbs in the marinade because it is discarded later.
