👨‍🍳 步驟

1. 1

   Preheat oven to 200°C (180°C fan/400°F/Gas Mark 6).

   💡 專業提示: Allow the oven to fully preheat before placing the lamb.
2. 2

   In a small bowl, mix chopped rosemary, minced garlic, olive oil, salt, and pepper. Rub this mixture all over the rack of lamb.

   💡 專業提示: Ensure an even coating for maximum flavor.
3. 3

   Sear the lamb rack in a hot, oven-safe pan for 2-3 minutes per side until browned.

   💡 專業提示: This step creates a flavorful crust.
4. 4

   Transfer the pan to the preheated oven and roast for 15-20 minutes for medium-rare, or until desired doneness.

   💡 專業提示: Use a meat thermometer: 55°C (130°F) for medium-rare, 60°C (140°F) for medium.
5. 5

   While the lamb is roasting, boil the cubed kumara in salted water until tender, about 15-20 minutes.

   💡 專業提示: Drain the kumara thoroughly.
6. 6

   Mash the cooked kumara with butter and warm milk until smooth and creamy. Season with salt and pepper to taste.

   💡 專業提示: Add more milk if a thinner mash is desired.
7. 7

   Once the lamb is cooked, remove it from the oven and let it rest for 10 minutes before carving.

   💡 專業提示: Resting allows the juices to redistribute, resulting in a more tender lamb.
8. 8

   Serve slices of the rested lamb rack with a generous portion of kumara mash.
