Tips for Cooking a 3 lb Pork Roast

Dry your pork – To ensure the roast is an adequate crispy crackling when cooked, you’ll need to dry your pork. To dry the pork, simply pat all the water out with a kitchen towel or leave uncovered in the fridge overnight.

You can make your own rub – if you can’t find a Rub for a pork roast in the market, no need to worry, you can easily make your rub at home. It only requires a few ingredients and will equally be as efficient as the regular store-bought rub.

Preheat your oven – while preparing the ingredients for your pork roast, you can simultaneously preheat your oven so you don’t have to spend much time in the kitchen. Preheat the oven to 480 degrees Fahrenheit for best results.

Tie the pork roast – although this is an optional step some people take, tying your pork with a kitchen string proves to be a little helpful in roasting pork. You can always get it ready-stringed from a butcher, too. Tying up the roast helps it to stay together when cooking.

Score your pork – roasted pork is known for its crispiness, and you wouldn’t want yours to be an exception, would you? For your pork to be more tender on the inside and crispy on the outside, you’ll need to score your pork.

Scoring your pork is simply creating deep grooves into the surface of the pork with a kitchen knife. This allows heat to move freely up the pork roast when cooking and it makes the scored parts more crispy because they’re thinner than the rest of the roast. You can also buy pre-scored pork if you find one in the market.

Also, when attempting to score your pork, try to avoid cutting the strings holding the pork roast. Ensure that you score the roast at the part facing upwards too.

How to position the meat – it’s always best to face the part of the meat which has more fat upward. This allows the fatty surface to cook better and turn out as a crispy and savory crackling when the roast is ready.

What kind of pork to use – since it’s just roast pork, you can use basically any part of the pig, although the loins are more suitable for this recipe. Also keep in mind that the butt, also known as the shoulder takes longer to cook. So if you’re preparing a butt roast you might want to extend your cooking time a little more to ensure it’s thoroughly cooked.

You can make incisionsfor some extra flavor, you can make shallow cuts in the pork and insert some fresh herbs and garlic into the holes, or since your meat is scored, you can stuff random areas of the roast with the herbs and garlic. Just ensure that this is done on the side of the pork that’s facing upwards and that the herbs and garlic are added generously to the pork.
