"Ok, the recipe as listed by the food network is totally totally wrong, just re-watch the episode (you can find it on youtube). Ground chili pepper can be found at a local Latin America Food Store, it is a finely ground medium heat chili pepper. This is NOT the same thing as chili powder.

Second, there is a reworked recipie in the comments here which is almost spot on. I've already cooked it twice to amazing success, however, I would advise backing off a little on the amount of ground chili pepper and crushed red pepper, and after two hours in, taste it and add more accordingly. I say this, not because I dont like heat, but because the heat level of the ground chili and crushed red pepper can vary quite a bit, and its always easier to add more.....

Also, I cooked mine for 5 hours. An initial 2 hour cook, tasting, adding more spices, then cooking for another 3 hours. Texture is amazing, so is the taste.

Happy eating!
