Oh man, I am all about brazing!!! I love braised short ribs and osso buko.
Braising is an art, a skill, a balance of temperature and time (a ballet) that is adjusted to accommodate the size and type of meat. I doubt you are going to achieve that in a crock pot. I dont know, maybe I am wrong?
If I was able to get a good finished product out of the crock pot I still wouldn't use it. Cant seem to justify using $7.35 in electric to cook a $3.00 piece of meat. Especially when I can get far superior results in a pressure cooker using about $.35 worth of electric.
The way I see it there are two kinds of people in the world. The ones that use a crock pot and the ones that would not use a crock pot. The ones that use crock pots
are the enemy. They are going to slow cook the earth until there is nothing left.
People that use crock pots are the same people that have an old rusting mustang on cinder blocks in the front yard. They sit on their sofa that is on the front porch and talk about how they been workin on the Mustang for the last 17 years.

You guys know Im kidding right?
Lets face it, debating is fun, and how many culinary and brewing things are debatable?
For sure the usefulness of the crock pot is.
