Heat a wok over high heat and pour in the vegetable oil. Add the dried chillies and habanero and toss for a few seconds until toasted, and then add the ginger and stir-fry briefly. Stir in the scallops and cook, tossing continually, for 1 minute. Pull the wok off the heat, add the tequila, and then return to the heat, tipping it to ignite the liquor. (If cooking on an electric stove, ignite the tequila with a long lighter, if desired.)
Toss the pan until the flame subsides and the tequila evaporates. Add the soy, vinegar, chilli oil, sesame oil and chives and toss until well combined and hot. Transfer to a platter and drizzle a little more chilli oil over the top, if desired. Serve immediately with steamed rice.
