She-Crab Soup, Carrying One Teaspoon of Flour

Published September 22, 2026 · South Carolina

Jump to Recipe

The whole thickening in the Charleston recipe is one teaspoon of flour for six servings, and the rest of the body comes from what is inside the crab.

The oldest printed version most people can actually read sits on page two of 200 Years of Charleston Cooking, 1930, recipes gathered by Blanche S. Rhett and edited by Lettie Gay. The heading over it says only Crab Soup, though the first line of the ingredients reads one dozen she crabs, and the page underneath says the soup belongs especially to the Rhett family, that it has been served for presidents and princes, and that it is prepared always now by Mrs. Rhett's able butler, William Deas, who is one of the great cooks of the world. The recipe is signed, in the book's own words, William's Recipe. The man at the stove is named in 1930; the South Carolina Encyclopedia entry that tells the story of President Taft eating this soup at Mayor R. Goodwyn Rhett's house in 1909 names no cook at all.

The same page explains the economics of the dish in one sentence: the crabman charges ten cents a dozen extra for she crabs with the eggs in, because the eggs are picked out and go into the pot with the meat, where they give what the book calls a delicious, glutinous quality. That is the thickening. The printed recipe uses two cups of milk, a quarter cup of cream and exactly one teaspoon of flour, and the book adds, fairly, that it is impossible to get she crab except in the laying season, and that tested in the New York Herald-Tribune Institute the soup was just as good made with any hard shell crab — only a little flavor of association would be lost.

Why this version works

Rice instead of roux. The South Carolina Encyclopedia describes the Charleston form of this soup as a Scottish crab bisque localized with boiled long-grain rice and the roe of blue crabs. A third of a cup of cooked rice blended into the milk gives the same coating body a flour thickening gives, without the raw-paste taste that Charleston cooks complain about loudest.

The milk never boils. Crab meat is already cooked and milk proteins curdle against acid and heat. Everything here is held just under a simmer, where the soup stays smooth and the crab stays in pieces instead of shredding into fibres.

Sherry goes in off the heat. Boiled sherry is cooking wine and tastes like it. Added after the pot comes off the burner, a dry amontillado keeps its nuttiness and does the job the printed tablespoon was doing in 1930.

Sieved yolk stands in for roe. Crab roe is a laying-season item and most fishmongers have never had it. Two hard-boiled yolks pushed through a sieve put back the fat, the faint mineral flavour and the orange fleck the eggs were there for, which is why the workaround has outlived the shortage.

Ingredient notes

Roe: if you can buy she-crabs in season and pick your own eggs, add them with the crab and drop the egg yolks. If not, the 1930 book already gave you permission: any hard shell crab, minus a little flavour of association.

Crab: a pound of lump or backfin, refrigerated rather than pasteurised if you have the choice. Pick it over on a tray for shell first; it is the only tedious part of the recipe and it cannot be done later.

Sherry: dry, amontillado or fino. Sweet cream sherry turns the bowl into dessert, and the bottle marked cooking sherry is salted wine that has been open in a warehouse for a year.

Milk and cream: whole milk and a half cup of heavy cream. Skimmed milk with more cream is not the same thing — the soup wants the body of whole milk throughout, not a thin liquid with fat floating on it.

Step by step

  1. Pick the crab. Spread the crab on a tray and go through it with your fingertips for shell, keeping the lumps whole. Keep it cold until it goes in.
  2. Blend the milk and rice. Purée the cooked rice with 1 cup of the milk until completely smooth, 30 seconds in a blender or a minute with a stick blender in a jug.
  3. Soften the onion. Melt the butter in a heavy saucepan over low heat, add the grated onion and cook 5 minutes without letting it colour.
  4. Warm the crab in butter. Add the crab, the white pepper and the Worcestershire, and turn it gently in the butter for 2 minutes — folding, not stirring.
  5. Build the soup. Pour in the puréed milk and the remaining cup of milk, bring it to the edge of a simmer, and hold it there 20 minutes. Do not let it boil at any point.
  6. Finish. Add the cream and the salt, give it 3 minutes more, then take the pan off the heat and stir in the sherry.
  7. Serve. Ladle into warm bowls and push the hard-boiled yolks through a sieve over each one.
If it broke or looks grainy, the heat went too high. Take it off, let it drop below a simmer, and whisk in a quarter cup of cold cream — that recovers most of it. If it tastes flat rather than broken, it is almost always salt: crab takes more than you expect, and a soup this pale gives you no visual clue that it needs it.

Storage and make-ahead

The soup keeps 2 days refrigerated. Reheat it over low heat, stirring, and stop well short of a simmer; a microwave will boil it in patches and curdle it.

It does not freeze. Milk, cream and picked crab all come out of a freezer with the texture wrecked, and no amount of whisking puts it back.

What to serve with it

Serve it small — a cup before a plate of something plain, not a bowl on its own. Benne wafers or dry toast, a green salad with a sharp vinaigrette to follow, and the rest of the sherry in a glass beside it.

Questions readers ask

Is claw meat good enough?

Yes, and it tastes more strongly of crab. It is darker and the soup will not be as pale, which matters only if you care what it looks like in the bowl.

What if I cannot get crab roe?

Use the sieved egg yolks and stop worrying about it. The 1930 book itself reports the soup tested just as well with ordinary hard shell crab, and it was written in the city that invented the dish, by people who could buy she-crabs off a cart.

Can I make it ahead for a dinner?

Make it to the end of the simmer, cool it, and refrigerate up to a day. Reheat gently, then add the cream, salt and sherry at the last minute — those three are what go dull overnight.

Can I thicken it with flour after all?

A teaspoon, whisked into the butter before the crab goes in, is what the Charleston recipe did and it will not hurt. A tablespoon or more is where the soup starts tasting of paste rather than crab, which is the complaint Lowcountry cooks have been making about restaurant versions for decades.
