Heat a baking-pan very hot. Put into it a tablespoonful of butter; then the oysters, which have been well drained. Let them cook in hot oven until browned. Have ready some toast cut into even pieces; soften them with some liquor from the pan; place three or four oysters on each piece, and pour over them the liquor from the pan, which should be reduced if too watery. Sprinkle with a little parsley chopped very fine.
