Step 1
Remove leg of lamb from the refrigerator (about 1 hour before roasting).
Step 2
Meanwhile, place all ingredients for the glaze in a small saucepan. Place over medium heat and bring to a simmer until slightly thickened, about 3 minutes; set aside.
Step 3
Preheat oven to 425°F (220°C).
Step 4
Using a small paring knife, make random small incisions about 1/2 inch (1 centimetre) deep into the surface of the lamb; tuck a sliver of garlic into each incision.
Step 5
In a small bowl, whisk together the olive oil, rosemary, salt and pepper; rub mixture over the entire surface of the lamb.
Step 6
Place lamb on a rack in a roasting pan and roast for 15 minutes.
Step 7
Reduce heat to 350°F (220°C) and roast for 30 minutes.
Step 8
Baste well with mint glaze; repeat basting after 15 minutes.
Step 9
Continue roasting until meat registers 125°F (52°C) on an instant-read thermometer for medium-rare, 135°F (57°C) for medium or 145°F (63°C) for medium-well - about 5 - 10 minutes longer. Cover lightly with foil and allow meat to rest for 15 minutes (temperature will continue to rise another 5 to 10 degrees while resting).
Step 10
While the lamb is resting, prepare the glazed vegetables.
Step 1
Trim the tops and bottoms off the radishes and reserve the greens; quarter the radishes into wedges.
Step 2
Cut the stems from the reserved greens and roughly chop; set aside.
Step 3
In a large skillet, melt 2 tbsp (28 g) of butter over medium heat. Add the radishes and carrots and cook, stirring frequently, for 8 minutes.
Step 4
Add the garlic and cumin; cook 3 minutes.
Step 5
Increase heat to medium high and add stock. Simmer until liquid has been reduced by half, 4 to 5 minutes.
Step 6
Add Redpath ® Dark Brown Sugar, white wine vinegar, salt and pepper; cook, stirring, for 1 minute.
Step 7
Add reserved radish greens and cook until just beginning to wilt.
Step 8
Carve rested lamb into slices and serve warm, accompanied by the candied vegetables.
*Make sure to allow the lamb to rest after roasting and before slicing it. This will help keep the meat juicy, and will also allow the meat to reach its correct internal temperature.
