Steps:

• Place chicken strips and cornstarch in a large resealable plastic bag. Shake to coat.
• Heat vegetable oil in a large skillet over medium-high heat. Add chicken and cook until golden brown on the outside and juices run clear, about 5 minutes on each side. Transfer to a paper towel-lined plate.
• Whisk together garlic, ginger puree, Sriracha, sesame oil, rice vinegar, brown sugar, and soy sauce. Add mixture to the skillet and bring to a boil. Reduce heat and simmer until sauce has thickened, about 3 minutes.
• Return chicken to the skillet. Add green onions and toss to coat. Cook over medium-high until heated through, about 2 minutes. Serve immediately.

Steps:

• Combine the sherry, ginger, soy sauce, 1 tbsp oil, brown sugar, corn starch, garlic, red pepper flakes, and beef in a resealable plastic bag and seal. Turn several times to coat and marinate 30 minutes at room temperature, or refrigerate for up to 24 hours.
• Heat a large wok or pot over high heat. Add 1 tsp oil. Lift the beef from the marinade with a slotted spoon, reserving the marinade. Quickly stir-fry the beef until lightly browned on both sides, about 1-2 minutes. Remove from the pan and set aside.
• Add the remaining oil and stir-fry the bok choy, shitakes, scallions, and carrots for 1-2 minutes. Add the reserved marinade, stock, water, and hoison sauce. Bring to a boil. Stir in the noodles and simmer until tender, about 8-10 minutes. Return the beef to the wok or pot, cooking just long enough for the beef to heat through. Finish with a few drops of Chinese hot pepper oil. Do not let it sit before serving, or the noodles with absorb the liquid and swell!
