Description

This Mizu Yokan is a refreshing and silky Japanese dessert made with just three simple ingredients—adzuki bean paste, agar-agar, and water. Light, naturally sweet, and perfect for pairing with tea, it’s a simple yet elegant treat.


Ingredients

Scale
  • 1 cup (250g) smooth red bean paste (Koshian)
  • 2 cups (500ml) water
  • 1 teaspoon agar-agar powder
  • 2 tablespoons sugar (optional, depending on the sweetness of anko)

Instructions

  1. Préparing the Agar-Agar
    If using agar-agar sticks, soak them in water for about 1 hour until softened. Squeeze out excess water and tear them into small pieces. If using agar-agar powder, skip the soaking and proceed to the next step.
  2. Dissolving the Agar-Agar
    In a medium saucepan, combine the agar-agar (pieces or powder) with 2 cups of water. Bring the mixture to a gentle boil, stirring constantly to prevent lumps. Let it simmer for 5 minutes or until the agar-agar has completely dissolved.
  3. Adding Sweetness & Flavor
    Slowly add sugar (if needed) and stir until fully dissolved. Then, gradually mix in the smooth adzuki bean paste (Koshian). Stir continuously over low heat until the mixture is smooth, fully blended, and slightly thickened.
  4. Pouring & Setting the Mizu Yokan
    Carefully pour the mixture into a shallow rectangular mold or dish (about 1-2 inches deep). Let it cool to room temperature, then refrigerate for at least 2 hours, or until fully set and firm to the touch.
  5. Cutting & Serving
    Once firm, gently remove the Mizu Yokan from the mold. Use a sharp knife to cut it into small rectangular or square pieces. Serve chilled with green tea or black tea.

Notes

  • Use premade Koshian for a silkier texture.
  • Always fully dissolve agar-agar before adding red bean paste.
  • Strain the mixture before pouring for an ultra-smooth finish.
  • Let Mizu Yokan cool at room temperature before refrigerating.
  • Best served chilled for optimal texture and flavor.
