- Mizu Shingen Mochi:
- 3/4 cup hot water
- 2 tablespoons white sugar
- 1 1/2 teaspoons agar-agar powder
- Strawberry Compote:
- 1/4 cup white sugar
- 1/4 cup water
- 1/4 teaspoon arrowroot powder
- 1 pound fresh strawberries, cut into quarters
- 1 lemon, zested and juiced
- Combine 3/4 cup hot water, 2 tablespoons sugar, and agar-agar in a saucepan; bring to a low boil. Cook and stir until sugar and agar-agar are dissolved, 3 to 5 minutes. Pour mochi mixture into a spherical mold and refrigerate until set, 6 to 12 hours.
- Mix 1/4 cup white sugar and 1/4 cup water together in a saucepan over medium heat; cook and stir until sugar is dissolved, 2 to 4 minutes. Add arrowroot and stir until dissolved, about 1 minute. Add strawberries, lemon zest, and lemon juice; cook and stir over medium-low heat until strawberries soften and start to release their juice, 5 to 10 minutes. Transfer strawberry compote to a storage container and cool to room temperature; refrigerate until chilled, about 30 minutes.
- Place mochi in a serving dish and drizzle strawberry compote over it.
