Homemade Wonton Soup

In a food processor, combine the shrimp, ginger, and shallot. Lightly process into a chunky paste. Combine in a mixing bowl with the ground pork, soy sauce, mirin, salt, rice vinegar, and red pepper flakes.
Working several at a time, lay a few wonton wrappers on a clean countertop or flat surface. Keep the remaining stack of wonton wrappers loosely covered with a clean kitchen towel or plastic wrap. Lightly brush the four edges of the wonton rappers with water and spoon about a tablespoon of filling into the center of each.
Fold the wontons in half into a triangle. Make sure no air gets trapped inside and that the edges are fully sealed. Then, fold the left and right corners across the center of the dumpling and press them together, like arms crossed. You will need to dab them with water to make the "arms" stick together. Repeat with the remaining wrappers and filling.
Bring a medium pot of lightly-salted water to a boil. Gently drop a number of dumplings (about 8 to 10 at a time) into the water and boil for about 5 minutes, until they float and are fully cooked. Use a slotted spoon to place them in a shallow bowl as you repeat until all the dumplings are cooked.
TIP: You will probably not need all of these dumplings for the soup. You can make them all and enjoy the extra on their own, or freeze about 10 of them, raw, for another time.

Combine the 2 cups water, stock, ginger, soy sauce, salt, and sugar and bring to a boil. Simmer for about 5 minutes. Taste for seasoning.
Add about 20 dumplings to the soup -- or more if you want, because they're just that good. If using, add the bok choy and spinach and let wilt before ladling into bowls and garnishing with fresh scallions.
