I slow cook it with various spices, herbs and a few veggies. The attraction of slow cooking is that you just put in there whatever you can gather from around the house- that makes it especially easy and very cheap to boot!An onion, couple of tinned tomatoes, some frozen mushrooms, dried tarragon, a bit of leftover red wine...Just fill with water and forget about it till the smell from the kitchen reminds you to return!!
Slow cooking makes brisket seriously tender.
I don't have a "crock pot" or whatever this device is called- my combination oven has a slow cooking function and that's where I stick a big pyrex full of stuff!
