Instructions

  1. Step 1: Rinse 1 cup (200 g) brown rice under cold water until water runs clear. Soak the rice in 2 cups cold water for 30 minutes, then drain.
  2. Step 2: Place the soaked rice and 3 cups fresh water into a heavy-bottom pot. Add 150 g peeled and diced purple yam (about 1/2-inch cubes).
  3. Step 3: Bring to a boil over medium-high heat, then reduce heat to low and simmer gently, uncovered, stirring occasionally, for 50-60 minutes until the rice and yam break down into a creamy porridge.
  4. Step 4: Stir in 2 tbsp fresh shikuwasa juice, 1 tsp grated fresh ginger, 2 tbsp chopped mitsuba leaves, and 1/2 tsp sea salt. Mix well and cook for another 5 minutes to blend flavors.
  5. Step 5: Remove from heat and let sit for 5 minutes before serving. The porridge should be thick, smooth, and fragrant with citrus and herb notes.
