Heat 1 tablespoon of the oil in a pan over medium heat and cook the onions until translucent. Pour in the cranberry juice and cook until absorbed, and then remove from the heat. Toss in the gorgonzola, grapes and mint to combine.
Preheat the oven to 200 degrees F.
Sprinkle the steak with salt and pepper or your favorite rub, if using. Lightly cover the meat with the gorgonzola grape filling, and then roll up the meat and tie it off with butcher's twine.
Make a sachet with cheesecloth with the coriander, cardamom and nutmeg. Heat the remaining olive oil in a pan over medium-high heat, and then add the braciola and sear until browned on all sides. Remove from the pan, and pour in a small amount of the red wine to deglaze. Add the garlic and shallots and cook until softened, and then pour in the remaining wine and bring to a simmer. Return the braciola to the pan with the spice sachet and let braise in the oven uncovered for 2 hours, turning once.
Remove the braciola from the braising liquid and let rest uncovered. Strain the braising liquid and cook in a saucepan until reduced. Remove the butcher's twine from the meat, slice and fan out on a plate. Dress with the reduced braising liquid and serve.
