Fill an 8 qt pot approximately 2/3 full with water. Bring water to a boil and add 1 1-inch knob of ginger crushed, ¼ cup rice wine, 1 t salt, & 3 scallions that have been crushed. Add chicken to boiling water (poaching liquid). Bring poaching liquid back to a boil, turn the heat down to simmer, cover the pot, and simmer for 15 minutes. At 15 minutes, turn off the heat and let the chicken sit covered for 45 minutes. Save the stock for soup or sauces.
Pieces of chicken can also be poached this way. Reduce time of simmer to 5 minutes and let chicken pieces sit covered in pot for 20-25 minutes.
Meanwhile, prep sauce. Shred ginger, dice the green onions, if you like it spicy, add ½ -1 jalapeno pepper, sliced. In a small bowl, combine soy sauce, stock, sugar, dry sherry and sesame oil. Set aside.
When chicken is done, remove from liquid and let sit until cool enough to handle. Cut chicken into serving pieces and place on platter.
Heat oil in a small saucepan until you can see wisps of smoke. Add ginger, scallions and peppers to the oil. Be careful, as mixture will sizzle. Remove from heat immediately and add soy sauce mixture. If the sauce clouds, return to heat for a minute. Add a dash of white pepper.
Pour sauce over chicken and serve immediately with plenty of rice!
The sauce can also be used for steamed fish or as a dipping sauce for seafood.
