Granddaddy's Ultimate Shrimp Boil

Ingredients:
20 lbs. Fresh Gulf Shrimp
5 lb. bag of Small Red Potatoes
6 Ears of Corn, Halved
1 Lb. Smoked Beef, Pork or Andouille Sausage, cut in 3 inch pieces
1 Stick of Butter
1 Onion, cut in wedges
1 Lemon, cut in wedges
1 Bottle of Granddaddy's Award Winning Cajun Seasoning
1 Bottle of Granddaddy's Award Winning Seafood Seasoning

Instructions:
Set up your seafood cooker outside and away from any structures. Fill the large stockpot halfway with water and bring to a boil. Add 90% of the seasoning (save some to shake on the finished product) and the butter. Next, add the potatoes, onion, and sausage, and cook for 20 minutes. Add the corn and cook for an additional 10 minutes. Finally add the shrimp and cook for 2 minutes. Turn off the fire. Remove the basket and dump the entire contents on a table covered with several sheets of newspaper. Sprinkle on the rest of the seasoning (a light dusting) and provide the lemon wedges and cayenne pepper for those who want it spicy.
ENJOY!
