Ingredients
2
lb cooked king crab legs in shell, thawed if frozen and shells split lengthwise
1/2
stick (1/4 cup) unsalted butter
1
large garlic clove, lightly crushed
1/3
cup medium-dry Sherry
1/8
tsp freshly grated nutmeg
2
tbsp finely chopped fresh flat-leaf parsley
1/4
cup fine dry bread crumbs
1/4
cup finely grated Parmigiano-Reggiano (1/2 oz)
Directions
1.
Preheat oven to 450°F.
2.
Remove crabmeat from shell, discarding cartilage, and cut meat into 1/2-inch pieces.
3.
Melt 2 tablespoons butter in a 1 1/2-quart heavy saucepan over moderately low heat, then add flour and cook, whisking, 2 minutes. Add milk in a slow stream, whisking, then add garlic and bring to a boil, whisking. Reduce heat and simmer, whisking, until béchamel is thickened, about 3 minutes. Remove from heat and discard garlic.
4.
Whisk together yolks, Sherry, mustard, nutmeg, cayenne, and salt in a bowl, then add hot béchamel in a slow stream, whisking. Pour mixture into saucepan and cook over very low heat, whisking constantly, until an instant-read thermometer registers 160°F, about 2 minutes. Remove from heat and gently stir in crabmeat and parsley. Divide mixture among 6 (4-ounce) ramekins.
5.
Melt remaining 2 tablespoons butter and cool slightly. Stir together melted butter, bread crumbs, and cheese with a fork, then sprinkle over crab. Put ramekins in a shallow baking pan and bake in upper third of oven until crab is bubbling and crumbs are golden brown, about 5 minutes.
7.
Deviled crab can be prepared (but not baked) 4 hours ahead and chilled, covered. Bring to room temperature before baking.
