Add cornstarch and salt to the shrimp.
Slice the soft tofu and place it at the bottom of a heat-safe plate or container.
In a bowl, crack the eggs and add water at a 2:1 ratio (water:eggs). Add chicken powder and a pinch of salt, then whisk until smooth.
Strain the egg mixture over the tofu to create an even layer. Place the shrimp on top.
Cover and steam for 10–12 minutes, or until the egg is fully set and custardy.
Garnish with chopped green onions.
Drizzle with soy sauce and sesame oil before serving for an extra flavor boost.
Enjoy with rice.
