Take a cucumber and cut it in pieces two inches long, then peel away the dark green skin for one inch, leaving the other inch as it was. Set up each piece on end, scoop it out till nearly the bottom and fill up with bits of cold salmon or lobster in mayonnaise sauce. Cold turbot or any other delicate fish will do equally well or a small turret of whipped cream, slightly salted, should be piled on top. This dish never fails to please.
