Procure the crabs alive, and put them in boiling water, along with some salt. Boil them for a quarter of an hour or twenty minutes, according to the size. When cold pick the meat from the claws and body. Chop all together, and mix it with crumbs of bread, pepper and salt, and a little butter. Put all this into the shell and brown in a hot oven. A crab shell will hold the meat of two crabs.
