Ingredients
- 1 rack Rack of Lamb (about 1.5 kg, ask butcher to remove the chine bone)
- 0.25 cup Shio Koji (store‑bought or homemade, used to coat the lamb generously)
- 4 tablespoons Unsalted Butter (softened for easy mixing)
- 2 tablespoons Fresh Thyme (leaves only, chopped)
- 1 tablespoon Fresh Rosemary (finely chopped, optional)
- 2 cloves Garlic (minced)
Instructions
Ask butcher to remove chine bone
Have your butcher remove the chine (feather) bone from the rack of lamb so the meat is easier to carve and cook evenly.
Time: PT5M
Marinate with shio koji
Generously coat the entire rack of lamb with shio koji, making sure every surface is covered.
Time: PT5M
Marination
Place the coated rack on a tray or rack and refrigerate uncovered for at least 12 hours (overnight).
Time: PT12H
Prepare for cooking
Using the back of a knife, scrape off excess shio koji rice, then pat the surface dry with paper towels.
Time: PT5M
Herb butter mixture
In a small bowl, combine softened butter, chopped thyme, rosemary, and minced garlic.
Time: PT5M
Render fat cap
Heat a large skillet over medium heat. Place the rack fat‑side down (pan cold) and cook until the fat renders and begins to brown, about 8 minutes.
Time: PT8M
Brown meat side
Flip the rack and brown the meat side over medium heat for about 5 minutes.
Time: PT5M
Butter basting
Add the herb butter to the pan, tilt to melt, and continuously spoon the melted butter over the rack for about 10 minutes, basting both the meat and the fat.
Time: PT10M
Monitor internal temperature
Insert a meat probe into the thickest part of the lamb; aim for 48°C. The temperature will rise to about 54°C during resting.
Time: PT2M
Final sear
Increase heat to high and give the rack a quick 2‑minute sear on each side to crisp the fat.
Time: PT2M
Rest the lamb
Transfer the rack to a wire rack and let it rest for 10 minutes before carving.
Time: PT10M
Carve and plate
Slice between the ribs into individual chops, garnish with a sprig of mint if desired, and serve immediately.
Time: PT5M
