In a large heat-resistant bowl, mix chili flakes, ground chili, white sesame seeds, salt, and white pepper.
Then, add white vinegar and edible oil. Give it a good stir and set aside.
In a large pot, heat up neutral oil until it's about 160°C.
Once hot, toss in some green onions, ginger slices, peeled garlic, chopped red onions, and fresh coriander. Let them sizzle for 2 minutes.
After frying for about 2 minutes, add Sichuan peppercorns, star anise, cinnamon stick, and bay leaves and continue frying until fragrant. Once done, take out the aromatics, leaving you with clean oil.
Slowly pour 1 scoop of hot oil into the bowl of seasoning and mix well. Repeat this step 2 more times, giving you a total of 3 scoops. This will ensure that the peppers are spicy and not dry.
For the finishing touch, add a little baijiu.
Let it cool a bit before transferring the chili oil to a spice glass jar with a lid.
