Carefully remove the stems from your fresh red chilies. Pop them into a food processor or blender along with the minced garlic, Szechuan peppercorns, white pepper, rice vinegar, salt, and your chosen sugar (palm, coconut, or brown). Pulse until you get a chunky, vibrant paste.
Pour your chosen oil (canola, vegetable, olive, or sunflower) into a small saucepan. Heat it over medium heat for about 2 minutes, aiming for around 350°F (175°C).
Gently add your chili-garlic paste to the hot oil. Toss in the star anise and cinnamon stick. Lower the heat to low and let it simmer, stirring occasionally, for about 5 minutes. Watch as the garlic turns a light golden, infusing the oil with incredible aroma.
Carefully take out the star anise and cinnamon stick. Let your amazing sauce cool completely to room temperature. If you like, stir in the optional sesame seeds while it's still warm. Once cooled, spoon it into a clean, airtight container. Store it in the refrigerator to enjoy for up to 6 weeks!
