Slow Cooked Sous Vide Pork Belly with Watermelon Salad

This unusual salad is sweet, salty, herby and a little spicy, with the most tender crispy-edged pork belly you'll ever try. It can mostly be prepared ahead of time, making it a brilliant dish for entertaining.
You'll need to start the pork two days ahead so it has a chance to cook and then chill and firm up.

Ingredients

For the pork

  • 2 lb boneless pork belly 1kg in a single piece, skin on (you’ll remove the skin at the end but I found it helped keep the meat’s shape while cooking)
  • 2 tbs fish sauce
  • 1 tbs Sriracha hot chilli sauce
  • 2 tbs brown sugar
  • 1 piece ginger a thumb sized piece, sliced
  • 1 lime juice only

For the salad and dressing

  • 4 lb watermelon about 1/4 of a whole melon, rind removed and cut into bite sized chunks
  • ¼ cup fish sauce 60ml
  • 1 tbs rice wine vinegar
  • 1 lime juice only, use 2 if your limes aren’t very large
  • 1 bunch watercress large stems removed (if you can’t get watercress, another soft leafy green will do, but it does lend a great peppery kick to the dish)
  • 1 bunch mint leaves picked
  • 1 bunch coriander leaves picked

Instructions

Cook the pork (1-2 days before)

  • To make the pork, mix everything except the meat together in a small dish. Place the pork into a resealable bag (I always double layer the bags for safety in case the seams split), add the sauce/marinade and close the bag, squeezing out as much air as you possibly can without squeezing the liquid out. This is done most easily by submerging the bag into cold water up to the seal, which displaces all the excess air so you can just seal it shut. Massage the marinade around inside the bag so it gets onto all of the meat’s surface.
  • Put your bagged meat into an oven tray, put it in the oven and set your temperature to 160⁰F/70⁰C, steam setting (100% humidity). Set the timer for 15 hours. If your oven isn’t plumbed make sure you check the water level of your tank occasionally, especially if you’re planning to go out (or sleep!).
  • When the cooking time is up, put the whole tray, bag and all, into the fridge to chill overnight (this makes it much easier to cut into nice clean slices).

Make the salad

  • Mix the fish sauce, lime juice and vinegar, then pour it over the watermelon and set aside to macerate while you get the rest ready.
  • Arrange the watercress and herbs on a serving platter.
  • Preheat a dry frypan over medium high heat. Remove ginger slices from pork and discard, then slice off pork skin and discard. Cut the meat into large lardons (see picture for size reference) and fry in batches on both sides to brown and heat through. The fat will render out as you do this so no need to add any extra oil. Lift the pieces out when they’re done, and don’t throw away the fat that’s left behind, it’s part of your dressing!
  • To assemble, scatter the melon and any dressing/juice over the leaves, then top with the hot pork and drizzle the fat from the pan over the whole platter. Serve immediately.

Notes

  1. You can easily double the pork quantity if you want leftovers to use for one of the above suggestions. The cooking time remains the same.
  2. If your watermelon isn’t particularly sweet you might find you want a teaspoon or two of sugar in the dressing. I haven’t specified it here as we’ve never needed it, but you can adjust to taste.
  3. When it comes to bagging the meat, I suggest you double bag so it doesn’t leak. I used two ‘sandwich size’ zip-lock/resealable plastic bags for this sized piece of pork. I don’t think it would be a big deal if it did leak a bit, but I was trying to seal everything really well to approximate sous vide/bag cooking without the hassle of having to use a vacuum sealer, which most of us don’t have at home.
  4. Lastly, I have made this dish a few times now and have tested the pork both at 70⁰C for 15 hours and 75⁰C for 12 hours. The 70⁰C version is the winner in terms of texture, but only barely – I’ve written the recipe for that but if 15 hours just seems way too long to wait for anything, by all means try the 12 hour option. Beware, if you do the cooking overnight you might find your oven’s water tank runs out before you get back to it, so be a bit careful with that. My 1 litre tank lasted a full 8 hours as long as I didn’t open the oven door during that time (there’s no need to), so I’m just giving warning that yours may be different!
