New York State’s Edible magazines are celebrating their Eat Drink Local week with a party at Chelsea Market. Tastings there will spotlight the 11 local ingredients they’re encouraging home and professional chefs to use this week. It’s also one of two places to prove that you’ve been taking their Eat Drink Local Challenge seriously. The other opportunity is on Oct. 7 at The Knitting Factory. A bounty of foodie prizes awaits the winners.
