The tenth annual Washington Farmers Market Tasters Choice Salsa Contest is this tomorrow (9/3). Market Master Bob Shepherd says contestants need to furnish a labeled quart of their own home made salsa by 4:45. He says sampling starts at 5:00 in Central Park. After that, tasters will be asked to vote on their favorites. Shepherd stresses that double dipping wont be allowed, and that everyone is invited to enter a salsa, or serve as a judge.
