Having boiled the crabs, extract all the meat from the shell, cut
it fine, and season it to your taste with nutmeg, salt, and
cayenne pepper. Add a bit of butter, some grated bread crumbs, and
sufficient vinegar to moisten it. Fill the back-shells of the crab
with the mixture; set it before the fire, and brown it by holding
a red-hot shovel or a salamander a little above it.
Cover a large dish, with small slices of dry toast with the crust
cut off. Lay on each slice a shell filled with the crab. The shell
of one crab will contain the meat of two.
