remove and discard the fat layer from the liquid,
The liquid turned to solid fat! I did braise it. Vietnamese Pork recipes don't crisp it afterwards. I think I just used pork that was too fatty or something. I wasn't following a recipe but it was something along these lines:
Vietnamese pork

Makes me sad. I hope I never say that. I have cooking disasters from time to time too. A few days ago I cooked pork belly Vietnamese style. It was horrible, far too much fat to eat. I let it go cold before getting rid of it and it was literally set completely in white fat.
If you render it down enough it will be delicious!
