The nervetti, or beef tendon stew, braising prep also starts early with the chopped up tendons braising in aromatics and wine for five to seven hours. The tendons are then put back in their own braising liquid and turned into a gelatinous terrine that can be thinly sliced into an onion salad. Risina beans from a small purveyor are prepped for a tuna toro dish, cooking down the show-stealing legumes for three hours.
