1 cup blueberries
¾ tsp. agar powder
¾ cup plus 2 Tbsp. soy milk, almond milk, or other nut milk
¾ cup amazake
1 Tbsp. vegetable oil
In a blender or food processor, pulse the blueberries until smooth. Set aside.
In a small skillet over medium heat, stir together the agar and 3 tablespoons of water until dissolved. Add the soy milk and bring to a gentle boil, then turn the heat to low and simmer, stirring frequently, for 2 minutes. Remove from the heat and stir in the amazake, oil, and reserved blueberry purée until well incorporated. Divide evenly among four serving bowls and refrigerate until thickened, at least 3 hours, or up to 12 hours. Serve cold.
