Preparing Boston Pork Butt for BBQ sandwiches & Brunswick stew

So, today Im thawing my 10 lb Boston pork butt in cold water. and will slow cook it in a crockpot for 10 hours over night.
I make my own rub to go on it:
brown sugar
dark brown sugar
Ceyenne pepper
Black pepper
Paprika
Granulated Garlic
Fresh garlic ( or minced garlic you can purchase & put in fridge)
Salt 
* you can add liquid smoke if you wish


I butcher some of the fat on the pork , rub it down well, I do drizzle some bbq sauce on it  and cook!
You know your pork is done cooking when it reaches a temp of 160 degrees F. 
Now, for my stew:
making it in a 5 qt crockpot 
 3 cups of the pork once it is done
2 cups shredded chicken ( u can use canned or bake or broil some)
1 cup ketchup
1 cup bbq sauce
1  8 oz can tomato sauce 


1/2  cup of slurry ( this is 1/2 cup cold water & 1 tsp cornstartch- mix it will before adding and stir it into stew, this will tighten the stew up)
1 can cream corn
1 can whole corn
1/3 cup brown sugar
salt and pepper to taste
* you can add onions if you wish 
Cook in your crockpot for 1-2 hours.
