1. Fill the Pot: Begin by filling a large stock pot with enough water to cover all the ingredients, usually about halfway full.
2. Boil the Water: Add salt and bring the water to a rolling boil over high heat.
3. Add Potatoes: Once boiling, add the halved potatoes and cook for approximately 10-12 minutes or until slightly tender.
4. Incorporate Corn and Sausage: Add the corn and sliced sausage to the pot. Allow to boil for another 5-7 minutes.
5. Add Seafood: Gently add the shrimp and crab legs to the pot. Cook for an additional 3-5 minutes or until the seafood is cooked through and turns pink.
6. Prepare Garlic Butter Sauce: While the seafood and vegetables are cooking, melt butter in a saucepan over medium heat. Add minced garlic, Cajun seasoning, and the juice of one lemon. Stir and cook for about 2-3 minutes until fragrant. Remove from heat.
7. Drain and Combine: Carefully drain the seafood and vegetables in a colander and then bring them back into the pot. Pour garlic butter sauce over the top and toss everything together to combine the flavors.
