Oyster Soup (Oysters teaspoonful salt)
100 oysters. 1 teaspoonful salt. 1 tablespoonful black pepper. 1/4 pound butter. Yolks of 3 eggs. 1 pint rich milk, perfectly fresh. 3 tablespoonfuls flour.
Separate the oysters from the liquor: put the liquor to boil, when boiled add salt, pepper and butter, then the flour, having previously made it into a batter. Stir all the time. When it comes to a boil, add the eggs well beaten, then milk, and when the mixture reaches a boil, put in the oysters; let them also just boil, and the soup is done. Stir all the time to prevent curdling.--Mrs.Judge M.
A nineteenth-century Virginia oyster stew, thickened with both a flour batter and egg yolks. It scales down cleanly, but the seasoning and the order of operations both need attention.
- The hinge: add the oysters last, brieflyEverything else is finished before the oysters go in, and they need only to heat until their edges ruffle — well under two minutes. "Let them also just boil" is the whole instruction; carried past that they tighten into rubber and leak liquor into the soup.
- Scale and yieldOne hundred shucked oysters with their liquor is somewhere in the region of two to four quarts depending on size, and will serve a dozen or more. A quarter of that (roughly 25 oysters, or about a pint of shucked oysters with liquor) with a scant half-cup milk, 1 oz butter, 1 egg yolk and a scant tablespoon flour gives four bowls.
- Black pepperA full tablespoon of black pepper for 100 oysters reads as fierce, but spread across the finished quantity it comes to roughly a teaspoon per quart. If you scale down, measure by the scaled amount rather than by eye, and use coarse-ground.
- Oyster liquorBottled shucked oysters rarely carry as much liquor as freshly opened ones. If the drained liquor is scant, make up the difference with fish stock or water rather than more milk, or the soup goes flat and sweet.
- The egg yolksBeaten yolks dropped into boiling liquid will scramble however hard you stir. Slacken them first with a ladle of the hot liquor, whisking, then return the mixture to the pot and keep it just below a simmer. The recipe's repeated "stir all the time to prevent curdling" is the period's substitute for temperature control.
- "Rich milk, perfectly fresh"Rich milk in 1879 means unhomogenised milk with cream still on it; use whole milk with a splash of heavy cream, or half-and-half. "Perfectly fresh" mattered because milk on the turn curdles instantly in a hot, salty, acidic broth — a real risk before refrigeration.
- The flour batterWhisk the flour with a little cold milk or water until smooth before it goes into the boiling liquor. Added dry it will lump, and there is no roux stage here to catch it.
- Salt lastOyster liquor is already saline and varies a great deal by oyster. Taste before adding the teaspoon of salt, especially if you have topped up with stock.
Housekeeping in Old Virginia (1879), compiled by Marion Cabell Tyree from contributions by named Virginia housewives — here "Mrs. Judge M." — appeared when Chesapeake oysters were one of the cheapest proteins in the eastern United States. The bay's beds supported an enormous dredging and canning industry through the second half of the century, and calling for a hundred oysters in a family soup was not extravagance but ordinary marketing; oysters travelled inland by rail in barrels and cans, and cookbooks of the period treat them as a staple rather than a luxury. The double thickening with flour and egg yolks arguably places this soup closer to the older English tradition of enriched white soups than to the plainer milk-and-butter oyster stew that later became standard in American kitchens, though that is a reading rather than a settled classification. Overharvesting and disease reduced Chesapeake oyster landings drastically in the following century, which is why a recipe of this scale now reads as astonishing.
