Here in Louisiana, crab boil spice bags, bulk dried boiling spice, or liquid crab boil are readily available; feel free to mix up your own spice combination by using your favorite Cajun seasoning or order the
commercial seasoning options online here. Rather than fresh, I like the taste and texture of frozen corn on the cob when boiled; I believe it soaks up the flavor better. Go figure. Feel free to add whatever you like to the pot (sausage links, etc.), but don’t crowd the pot before you add the crabs. Some like to dunk their crabmeat into drawn butter (a bit highbrow for me), cocktail sauce (too overwhelming for me), or without any sauce whatsoever (oh yeah, the natural sweetness shines through). Some folks add a bag of crushed ice to the boiling water, but I don’t; I save my ice for chilling a glass of bourbon to celebrate the occasion.
