How to Make It
Heat 1 teaspoon of the oil in a medium saucepan. Add the shiitakes, shallots and ginger and cook over moderate heat, stirring, until fragrant, about 2 minutes. Add the lemongrass, basil, cilantro, Chicken Stock and clam juice and bring to a boil. Reduce the heat to low and simmer for 25 minutes.
Strain the broth and return it to the saucepan. Boil over high heat until reduced to 1 cup, about 10 minutes. Add the coconut milk and simmer for 3 minutes. Stir in the sesame oil, season with salt and pepper and keep warm.
In a skillet, heat the remaining 1 teaspoon of oil until almost smoking. Season the scallops with salt and pepper and sear over high heat until browned on the bottom, about 3 minutes. Turn and cook until browned and almost cooked through, about 2 minutes.
In a steamer over a pan of simmering water, cook the shrimp and bok choy until the shrimp are just cooked through and the boy choy is bright green, about 1 minute. Transfer to a plate. Add the lobster tails and claws and steam until heated through, about 30 seconds.
Transfer the coconut broth to a blender and blend for 30 seconds. Put a tomato slice in each of 8 warmed soup plates. Set a scallop on each tomato slice and arrange 1 shrimp, 1 bok choy leaf and 1 lobster claw or tail half alongside. Spoon about 2 tablespoons of the coconut broth into each plate and serve.
