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.
Seafood Boil. You've maybe heard it called many names: Frogmore Stew, Beaufort Stew, Lowcountry boil, Louisiana Crawfish boil or a tidewater boil. Traditionally, you'll find them in places like Louisiana, South Carolina and New England, as well as some other coastal States that focus on their regional seafood and side dishes. There is no written rule as to what goes in the pot, but most agree that it should be well-seasoned!
