Luxurious Cornish coastal bake: sweet white and flavorful brown crab meat folded with crème fraîche, Dijon mustard, tarragon, lemon zest, and baked under a crunchy Cheddar-breadcrumb crust.
In a mixing bowl, gently combine brown crab meat with crème fraîche, Dijon mustard, lemon zest, lemon juice, tarragon, and spring onions.
Carefully fold in sweet white crab meat, checking for any residual shell fragments while keeping lumps intact.
Spoon crab mixture into shallow ovenproof gratin dishes or cleaned scallop shells. Toss breadcrumbs with grated Cheddar and scatter evenly on top.
Bake at 200°C for 12-15 minutes until bubbling and golden-brown. Serve with warm crusty buttered bread and lemon wedges.
