There’s no denying your checkered past. Gingham gets you every time. Which means there will be no stopping you at Picnic, a new country store in Fort Greene stocked with all the trappings of a fine spring outing. Proprietors Camella Ehlke and Marlon Aitcheson provoke wholesome fun (the couple also runs the well-appointed Breathe Inn) with organic snacks, toys for outdoors, and fresh-made sandwiches to go. You can wash down a hearty lunch (smoked white fish and herbs; grilled cheese with truffle oil and fig; avocado, tomato, and cheddar on eight-grain; smart dog on a bun) with ginger beer or lavender lemonade before taking a snooze on one of the African-print picnic blankets Ehlke sewed herself. On the shelves are Prokadima paddles, canteens, stunt planes, sidewalk chalk, Frisbees, jump ropes, kites, and other diversions. Sure to make picnicking a walk in the park. Picnic, 185 DeKalb Avenue, at Carlton Avenue, Fort Greene (718-855-8965).
