In a food processor, add seafood mixture, egg, and butter. Pulse until the butter is incorporated but still visible (small pieces). Place 1 tablespoon of mixture on a wrapper and bring up the sides going around the mound. Continue with the remaining mixture and wrappers. Drop, open side up, from 6 inches on a flat surface to flatten the shumai bottoms. Steam shumai for 8 minutes.
Into 4 soup plates, place 3 shumai each. Ladle 4 ounces broth around the shumai. Serve and enjoy.

Master Seafood Mixture:
In a food processor, add shrimp, bass, scallops, egg, ginger, and sesame oil. Pulse only a little bit to bring ingredients together. Transfer to a large bowl and fold in scallions and cilantro. Season with salt and pepper.
Lemon Grass Broth:
In a 2-quart casserole, saute onions, jalapeno, ginger, and lemongrass. Deglaze with fish sauce and reduce by 80 per cent. Add stock and dash of white pepper. Reduce by 20 per cent on a slow simmer, about 45 minutes. Strain and keep hot. Check for seasoning. Squeeze in lemon juice right before serving.
