Peter Hoffman is often credited as one of the pioneers of farm-to-table cooking (before it became a cliché) in New York, but the chef left the restaurant world last year, after closing his restaurant Back Forty West. On May 19, he’ll make his triumphant return — for one night, anyway. That night, the Wythe Hotel’s Reynard and owner Andrew Tarlow will host the chef for a pop-up dinner (tickets are $115) marking Calçotada, the Catalan festival celebrating (what else?) the harvest of spring onions called calçot. In the hotel’s backyard, he’ll be grilling lamb and, of course, calçots on a 36 Asador grill — and serving them with romesco, butifarra sausage, beans, and charred greens. Plus, there will be crema Catalana for dessert and unlimited cans of Scribe Una Lou rosé. Not a bad way to say what’s up to a chef you’ve missed.
