Thinly slice the red onion. Dice the garlic and ginger. Finely chop the green onions. Slice the ghost peppers in half.
Add the cinnamon stick, star anise, cloves, cardamom pods, and white sesame seeds into a saucepan. Toast on medium heat for 3-4min. Then, set them aside.
Add the avocado oil into the saucepan and let it heat up for about a minute or two. Very carefully spoon in the red onions, garlic, ginger, and ghost peppers.
Fry for about 4-6min. Then, carefully transfer the ingredients onto a plate lined with paper towel. Spread them out so that they will stay crispy (use this as a topping on other recipes).
Carefully add the green onions into the oil along with the toasted spices. When it begins to bubble, add in the gochugaru and salt. Let it cook for about a minute. Then, turn the heat down to medium low and simmer for about 15min.
Turn off the heat and allow the oil to cool. Then, carefully strain through a sieve and then into a jar. Keep the cinnamon stick and ghost peppers in the bottle. Store the oil in the fridge and enjoy for up to 4-6 months.
