CHILI OIL: Combine the Sichuan chili flakes, red pepper flakes, sesame seeds, sugar, salt, and garlic in a heat-proof bowl. Heat the avocado oil in a saucepan over medium-high heat until the oil starts to shimmer. Immediately pour the hot oil over the prepared ingredients in the bowl and stir to combine. Let cool, cover and store for up to 4 weeks at room temperature!
COMBINE: In a medium bowl, combine the cornstarch, cilantro, scallions, minced garlic, ginger, sesame oil, oyster sauce, soy sauce, bouillon, sugar, and white pepper and mix using a spatula, spoon, or chopsticks.
MIX: When combined, add the ground chicken and mix again. Do not over mix once you add the ground chicken otherwise the meat mixture becomes tough.
PREP: Line a large sheet pan with parchment paper (this makes it easier to remove the wontons later.) Grab a small bowl of water, and place the filling near you. Wet a small kitchen towel to keep the wrappers covered while wrapping. And a second wet towel to keep the wontons covered once wrapped.
FOLDING: On a clean cutting board, place a wonton wrapper in front of you. Fill the wrapper in the center with a heaping teaspoon of chicken filling. Grab the two edges closest to you and fold them over the filling to meet the other edge, sealing the edges around the filling. Then fold the empty portion of the wonton over the filling portion halfway before bringing the corners together and squeezing to seal. There are many other methods you can use, this is one is called the bonnet method, and it’s the one I find the easiest.
KEEP GOING: Place the wrapped wonton on the prepared baking sheet, cover, and continue wrapping wontons the same way. Place the damp cloth over the prepared wontons as you fold to keep them from drying out and cracking. (See note for freezing instructions.)
BOIL: Bring a large pot of water to boil. Once boiling, gently lower batches of wontons into the hot water (about 6-10 at a time depending on the size of your pot) Cook the wontons for roughly 4-5 minutes total. They should float to the top around 3-3.5 minutes and you want to let them cook for another 1-1.5 minutes after that happens. Gently remove the wontons using a slotted spoon to a serving bowl.
SERVE: Combine the prepared 1 tablespoon of prepared spicy chili oil with a splash of black vinegar (1-2 teaspoons), 2 tablespoons soy sauce and 1 teaspoons sugar to make a sauce. Drizzle this over the prepared wontons and serve!
