Twenty pounds of crawfish, aka mudbugs, is what Chef Besh asks for in this recipe. Actually, what he says is that it's customary to allow for 5 pounds per person—that's double what's called for in this recipe. Here, however, he feels pretty safe to assume that you'll do just fine with only twenty pounds, given the plethora of other ingredients—potatoes, sweet corn, sausage, and artichokes—that this recipe will easily satisfy eight voracious eaters.
