Remove heads from shrimp, peel, and devein.
Make the broth: Place shrimp heads and pork bones in pressure cooker with about 2 quarts of water (I fill my pot up to the 1/2 way marker). Lightly season with about a teaspoon each of salt and sugar, if desired. Cook on high pressure for 45 minutes.
While broth is cooking, prep the wontons. Mix ground pork, shrimp, and egg in a food processor or blender. Season as desired. I use a drop of sesame oil, a splash of soy sauce, a pinch of salt, pepper, and sugar, and one clove grated garlic and same amount of grated ginger. Mix until filling resembles a thick paste.
Scoop a teaspoon of filling into each wonton wrapper and fold the edges as desired. See instructions in above blog post for a couple folding options.
When broth is close to done, bring a large pot of water to boil. Blanch vegetables of choice for your noodle soup.
Remove vegetables and set aside. In the same pot, boil the wontons in batches until all are cooked. It should take about 4-5 minutes per batch.
While the wontons are boiling, prepare bowls of soup. Scoop finished broth into serving bowls, one per person. Add seasonings to taste. I like to add a drop of sesame oil and a splash of soy sauce, but see the blog post for other ideas.
When wontons are done, cook noodles in the same pot according to the package instructions. While noodles are boiling, place vegetables and 4-6 wontons in each bowl of prepared soup. Finally, add the noodles when finished. Garnish with green onions, if using. Serve and enjoy!
