From the authors: "Why this recipe works - In its ideal form, crab dip is a warm, decadent party pleaser full of creamy, meaty seafood and savory spices. Unlike other versions of this popular appetizer, ours has a high ration of crab to cheese, allowing the sweet crab flavor to come through. To make it even more party-friendly, we used a cast-iron skillet as an oven-to-table cooking vessel, which ensures that your guests will enjoy the dip while it's hot.
For a serving option that was sturdy enough to scoop into the rich dip without any need for a spoon, we made a quick batch of crostini from sliced baguettes. To make a savory base for the crab dip, we first cooked onion in the skillet, adding just a bit of Old Bay seasoning and coriander. We then removed the sautéed onions from the skillet and combined them with cream cheese, mayonnaise, and parsley. After gently folding the crabmeat into the mixture, we put the whole thing back in the skilled and baked it until it was warm and bubbly, with the crostini fanned around the perimeter. Do not substitute imitation crabmeat here. To soften the cream cheese quickly, microwave it for 20 to 30 seconds."
