Tips: Sichuan chili oil: A Sichuan spice blend is infused into the oil, which is mixed with chile pepper flakes (not fried). The oil can be strained and the flakes used separately.
Sichuan peppercorn oil: A fragrant finishing oil infused with essential oils extracted from the Sichuan peppercorn. It has a smoother taste than the whole spice yet enough zing to wake up the mouth.
Zhenjiang black vinegar: Sometimes labeled "Chinkiang," this delicately sour rice vinegar seasoned with sugar and salt is used in virtually all cold Sichuan noodle and vegetable sauces, and in other sweet and sour dishes.
