1.In a mortar or a small chopper, make a fine paste out of the garlic, cilantro stems/roots,
2.Place the ground chicken into a mixing bowl and add prepared paste. Add 2 teaspoons of fish sauce. Mix until homogenous; set aside. You can use 1 teaspoon soy sauce in place of 1 of fish sauce if you desire.
3.In a large saucepan combine broth with soy sauce, 2 teaspoons fish sauce and white parts of green onions. Bring to a boil and then reduce to a gentle boil. Scoop chicken mixture into 1-inch balls and gently drop into simmering stock. Repeat until all the chicken mixture is gone. Cook until dumplings float to the surface about 1-2 minutes.
4. Gently add the tofu cubes to the broth; return to a simmer, then add the remaining green onions and remove from heat immediately. Adjust the seasoning as necessary with more fish sauce or soy sauce.
5. Ladle soup into a serving bowl. Garnish with cilantro leaves. Some freshly-ground white pepper on top is optional, but recommended.
6. Is this blasphemous? I don't know, but it is delicious, add a handful shredded Napa cabbage and carrots to broth, simmer additional 2-3 minutes until vegetables are soft. Top udon or ramen noodles with broth, dumplings and vegetables. Garnish with cilantro and green onions. You can use a firmer tofu instead if serving with noodles. Hmmm...
