IMPORTANT - Use wide or large shallow pot so all chicken and ingredients can be placed in one layer! This will help all your chicken to absorb the flavor and the liquid will boil down fast. If you change ingredient amount, you will have to change seasoning amount or cooking time. The most challenging part of this recipe is being able to get the feel of how much the liquid should be boiled down before adding noodles so that the chicken and veggies are not too bland or not too salty. You can also marinate chicken in seasoning the day before before adding veggies to make it easier to control flavor.
Soak Glass Noodles in warm water for at least one hour (If not enough time, boil for about 6 min in boiling water and wash in cold water and drain)
Wash chicken. For large piece, make incisions so flavors will penetrate easily. (You can parboil and wash chicken to remove gaminess if chicken is not fresh.)
Place skin side down in a wide pot.
Add all initial seasoning ingredients. Add only 1 cup (for default serving size) of water here because you want the chicken to absorb strong soy sauce flavor first. (Another option: You can also add all the water here and store in the fridge overnight so the flavor gets absorbed in the meat.)
Bring to boil (took 7 min but may vary depending on amount and heat)
Once boiling, keep cooking on high heat UNCOVERED for 15 min
Add additional 1.5 cup of water, potato, carrot, onion. You can add 1 tsp of instant coffee for darker color (if you want restaurant style color).
Bring to boil again (took 3 min but may vary depending on amount and heat)
Once boiling again, cook on high heat UNCOVERED for another 15 min
Flip chicken and make room for noodles
Add noodles and cook on high heat UNCOVERED for 3 min (If you don’t have much liquid left, lower the heat)
Add starch water and cook on medium heat for 3 more min
Add green onion and red chili pepper before serving.
If not eating immediately, take out noodles right away and store separately. Otherwise it will soak up all the liquid.
The end result should be salty enough so you can eat this with plain rice. This is NOT a stew so there should be only a small amount of sauce at the bottom. Depending on the amount and heat, cooking time will be different so make sure you boil it down until there is good saltiness. If you feel like it's too bland, add more soy sauce and sugar gradually towards the end while tasting or use salt to finish.
