Golden fried radish cake cubes with crispy edges and savory interior are a dim sum staple. A family-friendly snack with fresh, umami flavor.
Peel and grate the daikon radish. Squeeze out excess moisture and reserve the juice.
Soak dried shiitake mushrooms until tender, then finely dice. Thinly slice scallions.
In a nonstick pan over medium heat, sauté mushrooms and scallions with 1 tbsp oil until fragrant, about 2 minutes. Add grated radish and reserved juice, season with salt, sugar, and white pepper. Cook over medium-low heat for 10 minutes, stirring to reduce moisture.
In a bowl, whisk rice flour with water until smooth. Gradually stir the hot radish mixture into the slurry, mixing thoroughly. Pour into a greased loaf pan.
Steam the mixture for 60 minutes over high heat. Let cool completely (preferably refrigerate for easier slicing).
Unmold and cut radish cake into 1-inch cubes. Heat vegetable oil in a large nonstick skillet over medium-high.
Add cubes in a single layer and fry, turning occasionally, until all sides are golden and crispy, about 6 minutes.
Transfer to a plate and drizzle with soy sauce or serve on the side.
