Clean the crawfish by rinsing thoroughly in cool water; if frozen, thaw in cool water for 20-30 minutes.

In a stockpot, cover ingredients with about 6-8 quarts of water, bring to a rolling boil, then add Old Bay seasoning, Cajun seasoning, potatoes, corn, and citrus.

Add sliced sausage and reduce to simmer for 15-20 minutes until the potatoes are fork-tender.

Add cleaned crawfish and corn, boiling for about 5-6 minutes until crawfish shells turn red.

Melt butter in a saucepan, add minced garlic and lemon juice and simmer for 3-5 minutes.

Transfer to a baking sheet, drizzle garlic butter sauce, toss, and serve family-style.
