01 - Mix crushed red pepper flakes and salt in a heatproof bowl; set aside.
02 - Place oil, dried chilies, Sichuan peppercorns, star anise, cinnamon stick, cloves, bay leaves, garlic, ginger, and scallions in a small saucepan.
03 - Warm oil over medium-low heat until aromatics gently sizzle, roughly 5 to 7 minutes, stirring occasionally to avoid burning.
04 - Lower heat and simmer for 8 to 10 minutes until oil becomes fragrant and ingredients turn golden, without burning.
05 - Remove saucepan from heat and carefully strain hot oil through a fine-mesh sieve into the bowl with chili flakes and salt.
06 - Allow the infused oil to cool to room temperature before transferring into a clean, airtight jar. Store in a cool, dark place for up to one month.
