Grape Fruit and Clams
Place four or five Little-Neck clams in the core-hollow, pouring over them a sauce made of horseradish, tomato catsup, salt, and a dash of tabasco, blended to taste.
A first-course conceit from the era when grapefruit was still a novelty on American tables: a halved fruit hollowed at the core and filled with raw clams in cocktail sauce. The raw shellfish is the problem, and it is not a small one.
- Raw clams, never cookedNothing in this recipe brings the clams to any temperature at all. Raw bivalves filter and concentrate whatever is in their water, which is why they carry Vibrio parahaemolyticus and V. vulnificus, norovirus and hepatitis A. The sauce does nothing: horseradish, catsup and Tabasco do not pasteurize shellfish.
- No sourcing standardShellfish sanitation when this was written was nothing like the present system: certified harvest waters, tag retention and continuous refrigeration were not assumed, and the recipe simply assumes clams are clams. Modern raw-bar practice depends entirely on those controls, none of which the instruction addresses.
- The acid is not a safeguardThere is a persistent belief that citrus juice or vinegar "cooks" shellfish. It does not kill the organisms of concern at the concentrations and contact times involved here, and in a grapefruit shell the clams are sitting in juice at room temperature — the direction people should not go.
- "Little-Neck"A small market grade of the hard clam, Mercenaria mercenaria, roughly one and a half to two inches, and still sold under that name. Four or five of them is a generous filling for a core-hollow.
- Tomato catsup of the periodCommercial catsup of the period was thinner, more vinegary and more variably preserved than the modern product; some brands still carried benzoate. The sauce as written is essentially a proto-cocktail sauce, and a modern one would read sweeter and thicker.
- If you want the dishFollow a current recipe from a source that specifies shellfish sourcing and handling, or eat it somewhere that does. The grapefruit-shell presentation is the only part of this page worth carrying forward.
Grapefruit entered American eating late — commercial shipment from Florida groves is generally traced to the 1880s, and it only became a standard breakfast and first-course item in the first decades of the twentieth century, which is exactly why a book of fruit recipes experiments this freely with it. The halved fruit with its core scooped out made a natural cup, and cookery writers of the period filled it with everything from crab to cherries to maraschino. Pairing it with a clam cocktail sits at the intersection of two fashions: the grapefruit half as a smart opening course, and the raw clam or oyster cocktail in a horseradish-and-catsup sauce that was becoming standard hotel and oyster-house fare toward the end of the century. The combination reads as novelty rather than tradition, and it did not survive; the sauce, essentially unchanged, did.
