Serves 1 to 2

Miso Butter

  • 2 tablespoons miso
  • 4 tablespoons butter

PREPARATION: Combine ingredients and stir until evenly incorporated. 

Sweet Potato

  • 1 large Japanese sweet potato
  • 1 teaspoon Maldon sea salt, divided
  • ½ cup miso butter
  • 1 tablespoon grated Parmesan cheese
  • 1 teaspoon brown sugar

PREPARATION: Bake sweet potato on a baking sheet at 325 degrees for 70 to 90 minutes, until softened and cooked through. When cool enough to handle, split potato in half lengthwise. Season with one-half teaspoon salt, then spread miso butter on potato and top with cheese and sugar. Set oven to broil and return potato to a baking sheet for one minute or until caramelized. Season with remaining salt.

NOTE: Umami salt, flavored with umami-packed dashi, can be used in place of Maldon salt. Sealey substitutes brown sugar with Japanese black sugar (black cane sugar). All may be purchased at specialty retailers.
