Do your usual crab boil. I start with potatoes first, remove them when tender, add corn, sausage crablegs in pot together bring back to a boil for about 10 mins. Turn off flame & add shrimp, after 10 min. remove everything from pot. For garlic butter, just sauté butter in minced garlic, oregano, basil. Pour over boil and sprinkle with cajun seasoning, paprika, & parley flakes.
