Chef’s notes
My first preparation check: Pour your three cups of oil into a large saucepan. Add the cinnamon stick, cardamom seeds, cloves, bay leaves, crushed garlic, ginger, and star anise, then slowly bring the oil up to heat. Keep the temperature low, aiming for around 120°C. Add the shallots as well, allowing the flavours to infuse gently without burning the garlic, which could turn bitter.
Ingredient swaps
Check the gluten-free status of the sauces, stocks and seasonings you use. A similar name does not establish the same ingredients or gluten-free status.
Why this recipe works
Get the chopped ingredients and measured liquids ready before you start. Keep the addition order in the method so each component gets its intended time in the pan or bowl.

Method
- InstructionsPour your three cups of oil into a large saucepan. Add the cinnamon stick, cardamom seeds, cloves, bay leaves, crushed garlic, ginger, and star anise, then slowly bring the oil up to heat. Keep the temperature low, aiming for around 120°C. Add the shallots as well, allowing the flavours to infuse gently without burning the garlic, which could turn bitter.
- Prepare a heat-safe bowl for the hot oil. Place the Korean chili flakes, toasted sesame seeds, swan peppercorns, and all remaining ingredients in the bowl. Once the garlic is a nice brown and the shallots are cooked, remove the saucepan from the heat. Carefully pour the hot oil mixture into the bowl with the other ingredients, doing this slowly as the oil will be very hot.
- Allow the oil to cool, then add the soy sauce. Once fully cooled, transfer the oil to sterilised jars or a large jar with a lid. Store in a cool, dry place. Enjoy – your next meal is about to get a serious flavour boost!
