# What You'll Need:
→ Red Bean Jelly Layer
01 - 14.1 oz (about 1 3/4 cups) sweetened red bean paste (anko), smooth 'koshian' preferred
02 - 1 1/2 cups water
03 - 1 1/2 teaspoons agar-agar powder
→ Matcha Jelly Layer
04 - 1 cup water
05 - 1 teaspoon agar-agar powder
06 - 2 tablespoons granulated sugar
07 - 1 1/2 teaspoons matcha green tea powder, sifted
# How to Make It:
01 - Combine 1 1/2 cups water and 1 1/2 teaspoons agar-agar powder in a medium saucepan. Stir to disperse the powder, bring to a gentle boil, then simmer 1–2 minutes until the agar is fully dissolved.
02 - Remove the pan from heat and whisk in the sweetened red bean paste until the mixture is completely smooth and homogeneous.
03 - Pour the red bean mixture into a rectangular mold (approximately 7 x 5 inches). Skim any surface bubbles with a spatula, allow to cool at room temperature for about 10 minutes, then refrigerate for 30 minutes to achieve a light set.
04 - In a clean saucepan combine 1 cup water and 1 teaspoon agar-agar powder. Stir, bring to a boil and simmer for 1–2 minutes until the agar dissolves completely.
05 - Reduce the heat, add 2 tablespoons sugar and whisk until dissolved. Gradually whisk in the sifted matcha powder until the liquid is uniform and free of lumps.
06 - Allow the matcha mixture to cool until warm but not hot to the touch. Gently pour it over the lightly set red bean layer to avoid disturbing the surface.
07 - Refrigerate the assembled block for at least 1 hour, or until completely firm to the touch.
08 - Run a knife along the mold edges if needed, invert to remove the yokan, and slice into bars or squares. Serve chilled.
