It all started because Alison Cohen couldn’t get good eggs. Spring through fall, she shops at the Grand Army Plaza Greenmarket, but doesn’t trek there in winter when it shrinks to only a few stands. She missed the eggs. Unlike peaches and corn, local eggs are available year-round. They just weren’t easy to get to. Sure, she could buy organic eggs in her neighborhood, but they weren’t of much quality. She preferred eggs laid the day before by pastured chickens, eggs with deep orange yolks and thick shells. She wondered if her favorite Greenmarket egg farmer might deliver to her neighborhood if she placed a large enough order. Her daughter attends PS 29, across the street from their home. Through the school’s wellness committee, Alison met other food-conscious parents and her egg co-op was born, er, laid. Fifty families, even the principal, paid in advance. The farmer, Nestor Tello, a former Brooklynite, agreed to deliver 50 dozen eggs to her stoop every other Monday morning. On the way to drop off kids, parents collect their eggs, which most agree are the best they’ve ever tasted. Says Cohen, “We sit on the stoop and people stop and chat. It’s a small town in the middle of the big city. That’s why we live in Brooklyn.” In June when school lets out and the harvest season begins, the parents will still get Nestor’s eggs—at the market.
