Thereof, what can I use instead of a crock pot?
As long as you are relatively familiar with the heat characteristics of your stove-top, or even oven, you can go ahead and use a regular old cooking pot with a lid. A casserole dish covered with foil in a low temperature oven will work fine too.
Beside above, can you use your oven as a slow cooker? Yes, you already own a slow cooker, and it's called your oven. While slow cookers have been helping us cook low and, well, slow for several decades, people have long been using ovens (electric or wood-burning), hearths and even pits in the ground to prepare food over many hours.
Likewise, can I use stove top instead of slow cooker?
Generally speaking, if it's a slow-cooker recipe for a large, tough cut of meat, then you can braise it on the stove or in the oven. Many soup and stews lend themselves to this process, and just like a slow cooker, you can do this on the stovetop just as well.
What is the difference between a crockpot and a slow cooker?
The pot of the slow cooker usually sits on a base that houses the heating element on the bottom, while Crockpots have their pots inside of a container (or crock) and get heating from all sides. Therefore, slow cookers heat up slower than crockpots, with the heat level higher on the bottom of the pot.
