Ed Schoenfeld, co-owner of RedFarm in New York City, often grabs a few cartons of rice before leaving his restaurant. He’ll let the rice chill overnight and then, for lunch the next day, chop an onion, some additional vegetables, and whatever cooked protein he has hanging out in the fridge. It’s usually something like bacon or chicken, but Ed’s even cooked fried rice using leftover corned beef and pastrami.
