Sounds delicious! Do you mind sharing the recipe?
Ah, that's a bit tricky as I don't tend to use a recipe; more of a make it up as you go type of cook. However, try this.
Marinade Recipe
20-30ml ml soy
1/4 chopped red chilli (I always freeze mine and then grate them, easier than chopping and stops them going off)
2 teaspoons chopped ginger (also frozen and grated with the skin still on )
juice of half a lime
1 clove finely chopped garlic
10ml runny honey
1 teaspoon Chinese 5 spice
3-4 shakes of Worcester sauce
1 finely chopped spring onion (including the green part)
Slice the pork belly into 1 inch thick steaks
Place pork into a large ziploc or tie bag
pour in marinade and leave in fridge overnight
1 hour before cooking remove from fridge to come too
Pour everything including the marinade in a pan and
Slow cook over indirect heat until the fat is rendered out (about 30-40 minutes)
Baste pork with the marinade as you go (it should go thicker and a bit sticky)
Turn up the heat and sear on a griddle or directly on the grate (you want to try and get the edges to catch and caramelise.
As I say I do a lot of it by eye and feel but that's half the fun.
If you want to make it stickier then add more honey to the marinade or add a bit while cooking.
Good luck and enjoy
