This is the recipe my grandmother always used for stuffing/dressing. I am posting this here so I don't have to hunt down my recipe every Thanksgiving and Christmas.
In a skillet sweat/soften the celery and onion till tender and transparent.
Combine breads and seasonings in a large bowl. Stir in vegetables and butter mixture and then add in chicken broth to reach the desired moistness you prefer. Normally I use about two cans. This can vary depending on how dry and absorbent your bread crumbs are.
At this point you can stuff a bird with the mixture but I tend to just place the dressing in a buttered casserole dish.
Bake at 350* for about 1 hour till desired doneness. I like the dressing moist inside and crusty around the edges.
