Nutella, that sinfully indulgent chocolate-hazelnut spread, turns 50 this year, and it’s come a long way, baby…And now, one can even find a few hazelnuts in the Northeastern United States, where they’ve never been successfully grown before. They’re standing in a Rutgers University research farm, an oasis of orchards tucked in between highways, just outside New Brunswick, N.J. “All the green leafy things you see here are hazelnut trees. But in the beginning, they all used to die from disease,” says Thomas Molnar, a Rutgers plant scientist who is in charge of this effort.
