Lump crab meat and silky egg ribbons float in a savory, thickened broth. This luxurious, protein-rich family soup is a banquet-worthy dish with delicate, refined flavors.
In a large pot, bring chicken broth to a gentle simmer over medium heat.
Stir in soy sauce, white pepper, and salt; let the flavors meld for 2 minutes.
Dissolve cornstarch in 4 tbsp cold water and whisk into the simmering broth, stirring constantly until slightly thickened.
Reduce the heat to low. Slowly drizzle the beaten eggs in a thin stream while gently stirring in a circular motion to create silky ribbons.
Add lump crab meat and scallions, cook on low for 2 minutes until crab is just heated. Finish with a drizzle of sesame oil before serving.
