Despite the chill in the air, spring is surely here as perennial food markets bloom again for the season: - With its penchant for all things artisanal, the Hester Street Fair, at Essex and Hester Streets on the Lower East Side, reopens on Saturday, bringing together food vendors (from Luke's Lobsters and Prohibition Bakery to Pies "n" Thighs and Ample Hills Creamery), indie designers, yogis and more. The fair will continue through October on Saturdays from 10 a.m. to 6 p.m. - Also making its debut for the year is the New Amsterdam Market, at the South Street Seaport on South Street near Peck Slip, on Sunday from 11 a.m. to 4 p.m. A bread pavilion featuring more than a dozen bakers, all of whom use local flour, helps kick off the season's first market. - It's opening weekend for the food vendors parked at the Red Hook ballfields, located near the corner of Bay and Clinton Streets in Red Hook, Brooklyn. Much of the Latin American fare is sold from 9 a.m. to 9 p.m. on Saturdays and Sundays. A food blogger bake sale on Saturday from 10 a.m. to 5 p.m. at the Brooklyn Flea, 176 Lafayette Avenue (between Clermont and Vanderbilt Avenues), in Fort Greene, Brooklyn, will benefit Share Our Strength.
