What's the best way to cook brisket in a crock pot using Claude's brisket sauce?

I don't know about Claude's but I can tell you of a recipe which is just pickling spices and 1/4 cup whiskey. I usually put it in a pot to cover it with water add a couple tsp pickling spices with whiskey and simmer for 4 hours. I suppose the crock pot is the same slow cooking. It has a good flavor and the aroma fills the house.
