Crawfish Boil
Method
Crawfish Boil
Purge the crawfish
Place live crawfish in a large cooler or tub and cover with cool water. Add 1 cup kosher salt and stir gently. Let sit 5–10 minutes, then drain and refill with fresh cool water. Repeat rinsing 2–3 times until water runs mostly clear. After final rinse, cover crawfish with fresh cool water and add 4 cups of ice to chill and keep them dormant while you prepare the boil. Drain shortly before cooking.
Prepare aromatics and vegetables
While crawfish are purging, scrub the potatoes and corn. Cut corn into thirds (or halves if very large). Halve the onions. Smash the garlic heads lightly with the side of a knife (leave skins on). Cut lemons in half; reserve one for garnish and quarter the others for the pot.
Bring the boil liquid to a rolling boil
In a large stockpot (12+ qt) or crawfish pot, add 6 liters of water, 1 cup crawfish boil seasoning, bay leaves, peppercorns, allspice, and the quartered lemons. Bring to a rolling boil over high heat, stirring so the seasoning dissolves. Taste a spoonful of the broth (carefully) and adjust seasoning—add up to 1/4 cup more seasoning if you want a stronger spice level.
Par-cook the crawfish
Drain about 20% of the seasoned liquid (or use a slotted basket) to lower the water level so the pot can accommodate the crawfish without overflowing. Carefully add the drained, purged crawfish to the pot. Bring back to a boil, then cook for 3–4 minutes just to turn the crawfish bright red. Stir gently to ensure even cooking.
Turn off heat and steep
Turn off the heat and allow the crawfish and vegetables to steep in the hot seasoned liquid for 15–20 minutes (longer for more intensely flavored crawfish). This step lets the seasoning penetrate into the crawfish, potatoes, corn, and sausage.
Finish and serve
Drain the pot using a large strainer basket or carefully tip the pot/transfer contents to a large serving tray. Toss with 4 tablespoons melted butter and chopped fresh parsley. Squeeze reserved lemon halves over the top and offer additional lemons, hot sauce, and crusty bread on the side. Serve immediately on newspaper or trays for a communal boil experience.
