Take some lobster or crab-meat and pound in a mortar. Mix with 1 tablespoonful of butter; season with salt and pepper, a pinch each of mustard, cayenne, nutmeg and curry-powder and moisten with lemon-juice. Cut small rounds of toasted bread; scoop out some of the centre; fill with the mixture and cover with a curry sauce. Sprinkle with fine bread-crumbs and let bake in the oven a few minutes. Serve hot.
