After eight attempts I have nailed the pork loin. This was a long trial and error process, mostly as a result of the internet not really having a clue how to cook this beautiful muscle, including some of the world’s best chefs. This is not a quick recipe and requires patience and number of days. The meat of the loin is very lean (despite it being covered in fat) so it overcooks quickly becoming tough and dry, and the crackling requires high temperature to, well, crackle. It is easy to overcook the loin to get the crackling right. The solution is brining, slow cooking, and then a blast of heat at the end.

The first step is to purchase the best pork loin you can get your hands on and then prepare a brine.I use a 5/2.5 percent salt/brown sugar brine, with added spices including: bay leaves, peppercorns, star anise, fennel seeds, black cardamon, and juniper berries. The brine is boiled in water to dissolve the sugar/salt as well as to help bring out the flavors of the spices. The brine is brought down to fridge temperature with ice (5 degrees c). To help the brine permeate the meat, it is injected throughout the loin and then placed in the brine for 24 hours (or longer if you wish). Pork loin is very dense and it takes a very long time for the brine to distribute throughout the muscle.

The pork knuckles are for a forthcoming recipe!

I love the infrared thermoeter

After 24 hours, the loin is removed from the brine, tied so that it is an even shape, then scored to help the crackling later. The loin is placed uncovered in the fridge for 48 hours to dry the skin. After 48 hours the loin is removed from the fridge at least an hour and half before putting into a 140 degree c oven. It is then cooked until the internal temperature reaches around 55 degrees. The internal temperature will rise to around 63 degrees c after resting. It took around 1 hour and 50 minutes with this loin to reach 55 degrees (the starting temp was 10 degrees) and the near-outside of the loin reached equilibrium temperature with the inside after 40 minutes.

The oven is then turned up to 260 degrees c and the loin is blasted for around 15 minutes.  This allows the crackling to form without overcooking the inside. While the loin rests for a final time the gravy is prepared by pouring off the fat from the roasting pan and then adding some Cider to deglaze. Once the roasting tray is deglazed I strain into a smaller pan and reduce until the desired flavor is reached. The loin is unbelievably moist inside, while the crackling is perfect.

Look at those little bubbles

I serve the loin with its jus, and braised red cabbage  which is very acidic, complementing the loin, and left over cider to drink

That’s granny smith apple as well as cider vinegar

Served on a bed of the braised red cabbage!

All in all, this is quite a complicated piece of meat to nail but definitely worth it.

There were many failures along the way prior to this which include:

• Insufficient brining time
• Insufficient skin drying time (i.e. no crackling)
• overcooking the inside in order to get good crackling
• Using the overhead grill (i.e. radiant heat), which technically produces better crackling, but also is a pain not to burn the crackling
• Not scoring the skin in nice 1-2 cm vertical lines. I really do not care to understand the science behind crackling, but I figure it is related to the water vapor exploding in/under the skin which can’t happen unless there is enough heat under the skin. The scoring in deep, vertical patterns allows the heat in.
• Rubbing the skin with salt/vinegar/oil is BS. I have concluded the only thing that matters is dry skin, with score lines.

Things which only help the overall product:

• Longer brining
• Injecting the brine into the muscle
• Longer drying
• Lower temperature cooking
• Higher temperature end blasting
