Equipment

Ingredients 
 

Part 1

  • 700 g slab skinless pork belly
  • 50 g Japanese leeks (naganegi) green part
  • 50 g ginger root thickly sliced
  • 3 cloves garlic whole with skin removed
  • 100 g yellow onion(s) roughly cut
  • 1 tsp rice vinegar

Part 2

  • 50 ml sake
  • 1 tbsp mirin
  • 250 ml pork stock from part 1
  • 150 ml soy sauce
  • 30 g sugar

Instructions 

Part 1

  • Take 700 g slab skinless pork belly and pierce both sides with a fork.

  • Dry the pork belly with a paper towel and roll. Start with the thinnest side and roll it up, secure with string or meat netting. (See video for how to tie with string.)

  • Place the pork into a deep pot, fill with cold water until the pork is just about submerged. (It's okay if the highest part is slightly poking out the top.)

  • Heat a frying pan on a medium-high heat. Once it's hot, add the pork belly to the pan and lightly char the outside. Keep turning the pork to make sure all the edges are evenly charred.

Notes

Remove the ginger, spring onion and garlic at the end of the simmering time and store leftover pork stock in the fridge for up to 1 week or 1 month in the freezer. You can use it for soups and broths.
You can soak boiled and peeled eggs in the ziplock bag with the leftover broth to make ramen eggs. Scoop out the pork fat before adding the eggs.
The chashu pork can be kept in the fridge for 3 days or 1 month in the freezer. I recommend slicing it first for convenience.
Rolling the pork belly is for decoration and is optional. You can still make delicious chashu without rolling it. If you don't roll it, reduce the cooking time to 45 mins on each side. (1 hour 30 minutes total)
