Spices: Combine all ingredients together in a small bowl and set aside.
Bring 3 gallons of water to a soft boil along with the spice blend, lemons, bay leaves, thyme, and onions. Note: the water should be as salty tasting like the ocean so you may need to add more in there.
Next, add in the potatoes and cook for 4 minutes before adding in the corn. Cook for another 4 minutes.
Add in the sausage and cook for 4 minutes and then add in the clams and cook for 4 minutes.
Finally, turn the heat off completely and add in the shrimp and cook for 8 to 10 minutes or until the shrimp is cooked and the clams have opened.
Drain the shrimp and clam boil and serve on a newspaper or a large serving platter.
