The once unsavory sauce, having aged a few years, was surprisingly delicious! Once bottled, its popularity spread across Europe and came to America in 1839 when businessman John Duncan ordered a small shipment of the sauce. Since then, Lea & Perrins Worcestershire Sauce has been used in many recipes like those seen here.
