What Is A Slow Cooker?

You may recognize it better if I refer to it as a crock pot. Technically, “crock pot” is a registered trademark of the company that makes slow cookers. The crock pot is a brand name slow cooker. “Slow cookers” are the actual name of the appliance. They are stand-alone, plug-in pots that cook at lower temperatures than regular types of cooking. They also cook for much longer periods of time.

The benefit being that meats are very moist and “fall off the bone” tender. Meats as well as other foods don’t need to be watched, stirred, or tended to once in the slow cooker.

In fact, removing the lid to check on the food is not suggested. If you lift the lid, you’ll need to add 15 minutes to your cooking time for every time you lift the lid. Lift it twice? That’s an extra 30 minutes you’ll need to add on to your cooking time. So fight that urge and just let it cook. The only time it’s okay to lift the lid is at the end of the cooking time. If a recipe gives you a range, such as 6-8 hours (like in this recipe), you can lift the lid at the 6-hour mark to check the food with a thermometer.

How To Use A Slow Cooker

These countertop appliances are fairly straightforward. Put your food in, cover with a lid and turn it on to either low or high temperature for the amount of time specified in the recipe you are using. Some slow cookers are digital and will offer a timer that will then switch to a warm, holding mode until you come to check on your food. Older, manual slow cookers will have a knob you turn to your selected low or high temperature. With these, you’ll want to keep an eye on the time yourself. But no matter which one you have, the way you use it is still the same. Put the food in, put the lid on and set it to cook! No stirring, no checking on the food, no adjusting the temperature. Just turn it on and let it cook. Easy!

What Is Pork Loin?

Pork loin is meat cut from the animal along the rib area between the legs and shoulders. It’s typically sold wrapped with string and should not be confused with tenderloin which is a different cut of meat. A loin cut can be cut into steak-like slices when cooked. Tenderloin lends itself to much smaller cuts at the dinner table.

Still confused? Here’s a YouTube video that will show you the difference between pork loin and pork tenderloin.
