Essential Ingredients and Their Roles
Key Ingredients (材料)

Step-by-Step Instructions
Step 1: Prepare the Broth
Pour the water into a medium pot and add white dashi, light soy sauce, salt, and dashi powder. Heat over medium heat until the broth gently boils. Add the bean sprouts and simmer briefly until they soften. Stir in the dissolved potato starch and mix well until the soup lightly thickens.
Step 2: Add the Egg
Lower the heat slightly. Slowly pour the beaten egg into the soup in a thin stream while gently stirring in one direction. Allow the egg to set into soft ribbons before lightly mixing once.
Step 3: Add Tofu and Crab
Reduce the heat to low. Add the silken tofu and gently break it into large pieces using a ladle. Add the crab-flavored kamaboko and warm everything without boiling.
Step 4: Finish and Serve
Turn off the heat and add the thread agar. Let it soften in the hot soup. Serve in bowls and top with mitsuba or green onion. Add a drop of sesame oil if desired.
Assembly and Presentation
Start with the broth as the foundation, then layer textures carefully. The egg should float softly, the tofu should remain visible, and the crab pieces should be spread evenly. Serve the soup in simple Japanese bowls to highlight its pale color. A small green garnish on top adds contrast and freshness without overpowering the dish.
