Add a little oil to the inner pot, and select Sauté.
When the display indicates HOT, add the onion and garlic, and cook for a few minutes until softened, then remove the onion and set aside.
Add sugar to the inner pot with 60ml water, and continue to cook until the sugar turns into a dark caramel. Add an additional 180ml water, then press Cancel and add the fish sauce, soy sauce, star anise and cooked onions.

Select Pressure Cook and set the time for 19 mins (2,5cm thick pork belly) to 22 minutes (4cm thick pork belly), and press Start.
While the pork cooks, make the onion pickle. Add the red onion and thinly sliced chilli to a bowl. Squeeze over the juice of 1 limes, then add your fish sauce and sugar. Toss the onions to coat them in the dressing and set them aside to soften and pickle.
When the cooking program finishes, allow the pressure to release naturally for 10 minutes before quick releasing the remaining pressure. Remove the pork from the broth, then press Cancel and select Saute again until the sauce reduces.
