In a large bowl add annatto oil, lemongrass, ½ red onion, 2 smashed garlic cloves, vinegar, soy sauce, fish sauce, sugar, salt, and pepper. Mix to make a marinade, then rub the pork belly with this marinade and cover with a lid. Refrigerate for at least 30 minutes or, for best results, overnight.
2. Step
Grill your marinated pork belly until it is cooked, about 10 minutes, flipping a few times for good color.
3. Step
Cool the pork belly for a few minutes and chop into small pieces.
4. Step
In a bowl, add the pork mixture and add more (3 tbsp) vinegar, (3 tbsp) soy sauce, and red onion for that extra sour and salty traditional flavor.
5. Step
Broil for 5 minutes or until crispy.
6. Step
Garnish with an egg on top, remaining onion, green onions, and red chili peppers. Add as little or as much red chili to make spicy sisig.
