For the Miso and Sake Marinade:

  1. Trim lamb of any fat and gristle. Cut it into two logs and tie with butcher twine to hold its shape.  Place in a non-reactive container.
  2. Add all of the ingredients for the marinade to a bowl and mix to combine. Pour mixture over the lamb.  Let marinate for 6 to 8 hours, refrigerated. 
  3. Remove lamb from marinade and wipe off excess marinade. Place on a roasting pan and roast in a 375°F convection oven.  Cook until desired doneness.  Remove from oven and let rest.

For the Roasted Root Vegetables:

  1. Place all of the vegetables in a bowl and toss to evenly distribute with the oil, salt, and pepper.
  2. Spread out on a sheet pan and cook in a 350°F convection oven for 20 minutes. Be sure to stir vegetables halfway through the cooking process. When done, remove from oven and hold hot.

For the Mashed Potatoes:

  1. Steam potatoes until cooked through, about 20 to 25 minutes.
  2. Place potatoes in a mixer. Add the butter, milk, and salt.  Mix until creamy and all lumps are gone.
  3. Stir in the charred scallions and miso. Hold warm.

For the Sweet Soy Sauce:

  1. Mix the cornstarch and water together and set aside.
  2. Add the soy sauce, mirin, and sugar to a pan. Bring to a boil over medium-high heat. 
  3. When boiling, stir in the cornstarch mixture to thicken. Lower to a simmer and let cook for 30 seconds.  Hold on side hot.

For the Ginger-Scallion Sauce:

  1. Mix all of the ingredients together. Hold cold in refrigerator until ready to use.


To Plate:

  1. Place 4 oz of root vegetables to one side of the plate.
  2. Slice the lamb and lay 6 oz of lamb over the root vegetables.
  3. Place 4 oz of mashed potatoes on the other side of the plate.
  4. Drizzle the lamb with 1 ½ tsp sweet soy sauce and 1 tsp of ginger-scallion sauce.
  5. Garnish the top of the lamb with a pinch of julienned scallions.
