Rinse the red beans and remove any broken ones. Place them in a thick-bottomed pot with 4.5 cups of water and cover. Bring to a boil over medium heat for about 10 minutes, then reduce to low heat and simmer for approximately 1 hour and 30 minutes until the beans are very soft and tender. Alternatively, use canned sweetened red beans to save time.

Prepare the fruit: Peel the mango and cut it into small pieces. Chop the strawberries into small pieces, about half a cup.

Make the rice cake: Mix together 0.25 cup sweet rice flour, 1 teaspoon sugar, a pinch of salt, and 3 tablespoons of water. Cover with plastic wrap, leaving small gaps for steam to escape. Microwave for 1 minute.

Remove the heated rice cake mixture and gently knead it with roasted soybean powder until smooth. If it's too sticky, add a little water to help combine.

Assemble the bowl: Place shaved ice in a bowl and drizzle with milk. Top with the prepared red beans, mango, strawberries, and rice cake pieces.
