This ragù stands apart from most with the addition of fennel seeds, ground allspice, and habanero hot sauce. Like most great braises, it tastes even better after a day or two in the fridge, making it a great do-ahead dish for entertaining. Be sure to look for meaty short ribs; they can sometimes be skimpy, consisting of mostly bones. The ragù is topped with gremolata for a bright, fresh finish. Traditional gremolata is made with parsley, garlic, and lemon zest, but here the lemon is swapped out with orange zest, a nice match for the fennel and habanero in the ragù.
