  3. Place the potatoes flesh side down on an aluminum-lined sheet tray and roast in the oven for 30-35 minutes until the flesh is fully cooked and is easily pierced with a fork.
Make the miso butter sauce
  1. While the potatoes are roasting, mix the miso, sake, mirin, and granulated sugar in a small bowl until combined.
  2. Add the sauce to a small saucepan and cook on the stove over medium-low heat for five minutes, stirring very frequently. Make sure that you scrape the bottom of the pan often to move the sauce around and prevent scorching.
  3. Add the butter to the sauce and cook for an additional three minutes, stirring very frequently.
Broil the potatoes and serve
  1. Once the potatoes are finished baking, remove them from the oven and turn your oven’s broiler to high heat.
  2. Flip the potatoes over on the sheet pan so that they’re cut side up and use a pastry brush to apply the sauce on top of the potato flesh.

  3. Broil the potatoes in the oven for 1-3 minutes until the glaze is beginning to caramelize.  Check the potatoes frequently to avoid burning them.
  4. Once the potatoes are done broiling, place them on a serving plate and garnish them with the sliced scallions and sesame seeds, and serve.
