The best cut of pork for roasting

Pork leg, shoulder, or loin all make good joints for roasting. A piece of meat that's been boned and rolled is easiest to carve, and you might want to consider investing in a sharp knife.

As, when roasting the pork, you'll need to pierce the flesh. If the juices run clear, the pork is cooked; if it's still pink, it needs cooking for longer. Generally, outdoor-reared, free-range pork has a thicker layer of fat, which keeps the meat moister during cooking.

Do you cover pork when roasting?

If you're cooking a joint of pork, which has a fatty layer of skin you want to make into crackling, definitely do not cover your pork . It will make the skin soft and chewy.

Some joints of meat require covering to ensure that they do not dry out or brown too heavily. This isn't a problem with roast pork because the fat keeps it lovely and moist and you want the top of the skin to crisp up. If you remove the skin to make crackling separately then you might want to cover the meat to stop it from burning at the end of cooking .

Once you have finished cooking the roast pork , you might w ant to cover it to keep it warm when resting. Resting is important because it makes the meat juicy and more succulent. We prefer to take the crackling off before covering it in foil so that any steam com ing off the joint doesn't cause the crackling to go soft.

How long does it take to cook a 1kg or 2kg joint of pork?

As a general rule of thumb, it takes 30-35mins per 500g plus around 30min on high at the beginning to cook a joint of pork. If you are used to lb rather than grams then 500g is just over 1lb. The high temperature at the beginning is important because it gives the crackling a good head start before cooking the meat.

1kg of a joint of pork will take 1hr to 1hr 10 minutes + 30 minutes high at the beginning
2kg will take 2 hr to 2hr 20 + 30 minutes high at the beginning

If you have a meat thermometer, check to ensure the pork is at least 75C. Other meats will not need to be as hot but it is very important that pork is cooked properly. The UK Food Standards Agency says; "Pork needs to reach an internal temperature of 75C for 2mins in order to kill off any harmful bacteria" Pork is safe to eat as long as you cook it properly.

What temperature should roast pork be cooked at?

Our Test Kitchen recommends that you give pork an initial heat blast at 220C/Gas 8 for 30mins before reducing the heat to 180C/Gas 4 for the rest of the roasting time (30mins per 500g/1lb).  This is for pork roasting joints such as rolled shoulder, leg, or pork loin.

Some joints of pork, for example, pork belly, are cooked for much longer at the same temperature of 180C/Gas 4. Jamie Oliver cooks his pork belly for up to 1hr per kg but gives a slightly longer heat blast at the beginning – around  40-50mins. In Gordon Ramsay's honey glazed ham recipe he cooks his slow roast pork belly for 2.5hrs per kg with no heat blast.

If the skin hasn't become crispy by the end then you can put the heat up to 220C for a further 20-30mins but be careful not to overcook the meat. Our Deputy Food Editor, Rose, likes to remove the skin from the meat at the end and put the skin back in the oven on its own (while the meat rests) at a higher temperature to make sure it's super crisp.

How to make pork crackling

The key to crackling is to make sure the skin is super dry. You can achieve this in a number of ways. Deputy Food Editor, Rose Fooks, likes to store the joint in the fridge overnight after scoring the skin to really dry the skin out and then get it out an hour before cooking to ensure an even cook.

Food Director, Elisa, likes to pour boiling hot water over the skin before cooking then pat dry again with a tea towel before re-seasoning and roasting immediately. Our Food Editor, Samuel, is always careful when scoring the skin to ensure that he doesn't cut through to the meat which can release juices onto the skin and stop it from crisping up.

If the skin is struggling to get crispy then you can, as Rose does, separate the skin from the meat and cook it at a higher temperature whilst the meat rests.
