- 1L sunflower oil
- ~140g Korean chilli flakes (best substitute for erjiangtao colour)
- ~50g other dried chillis, a mix of grinds from very coarse to very fine
- Maybe half a cup (?) sesame seeds
- ~5 star anise
- ~8 green cardamom
- 2 cao guo, halved
- 2 large pieces cassia bark
- 1 tbsp fennel seeds
- ~8 tbsp good quality Sichuan peppercorns
- 2 spring onions whites
- 2 thumb-sized pieces of ginger, slightly crushed
- 2 cloves garlic, slightly crushed
- Heat about 40% of the oil over medium-low heat in a large saucepan, with all the ingredients except the chillis, sesame seeds, and 80% of the sichuan pepper.
- Wait until the wet ingredients are about to burn, then remove them. Wait for the oil to reach about 180°C.
- Add the chilli, sesame seeds, and remaining Sichuan peppers and stir vigorously. They will foam up a lot - make sure the pan is big enough. Before the chilli burns (5-10 seconds) pour in the rest of the oil to stop the the process.
- Decant: these quantities of oil and chilli will occupy about 1.2L volume.
