A dinner party-worthy recipe for roasted rack of lamb that's cooked alongside root vegetables and served with a vibrant honey orange pan sauce.
At least 3 hours ahead of time, but preferably the night before, prep the spice rub. With a mortar and pestle or small food processor, grind cumin seed into a powder. Add garlic and sea salt, and mash into a paste. Fold in citrus zests and thyme leaves. (Reserve juice of orange used for zesting.) Rub both racks of lamb all over with spice mixture. Cover and refrigerate for at least 3 hours or preferably overnight.
Toss vegetables with a tablespoon of olive oil and sprinkle with sea salt and pepper. Arrange on bottom of roasting pan, set roasting rack in place and place seared racks of lamb on top with the bone side facing down. Roast 12 - 17 minutes, or until the internal temperature reaches 130 (for rare) or 135 (for medium-rare).
Rest lamb on cutting board – the temperature of the meat will continue to rise as lamb rests. Remove roasting rack, turn vegetables, and slide back into the oven. Cook vegetables another 10 minutes, or until tender, while lamb rests.
While lamb rests, set the same skillet used earlier to sear lamb over medium heat. Add shallots and a drizzle of olive oil (enough to make 2 tablespoons fat – there should be some accumulated fat from searing the lamb), and cook until shallots are translucent and a deep golden brown, about 5 minutes. Add 3/4 cup wine, orange juice, 2 tablespoons zest slivers (reserve remaining zest for a garnish), and honey. Cook, stirring frequently, as sauce bubbles rapidly and thickens considerably, eventually turning a deep golden brown, about 15 minutes. Once sauce has reduced and thickened to a saucy consistency, turn heat to low. If needed, adding a little at a time, add up to another 1/4 cup wine to thin sauce.
To carve lamb rack into chops, set rack upright with rib bones facing up. Slide a sharp knife between each of the rib bones. Arrange roasted vegetables and lamb chops on a large warmed platter. Garnish with sprigs of thyme, reserved orange zest, and pomegranate arils. Serve with orange sauce.
