Oven safe pot directions (from Joshua’s video): Bring the liquid up to a boil, then reduce it down to a simmer and cover loosely with a lid (don’t close the lid entirely). Put it in a 300 Fahrenheit/150 Celsius degrees oven for 3-4 hours. NOTE: I did not try this method, so I am just writing down here what Joshua said for your convenience. Please also note that we have used pork bellies without skin and sliced instead of the whole 900 grams pork belly with skin that Joshua used, so I would think that less oven time is required.
