What ingredient gives she-crab soup its name?

Crab roe gives she-crab soup its name. Traditional versions use the roe of a female Atlantic blue crab, producing the soup’s characteristic orange color and adding a rich, briny flavor.

She-crab soup is a creamy regional specialty of South Carolina’s Lowcountry, especially associated with Charleston and Savannah. It is typically made with crab meat, crab or fish stock, milk or heavy cream, and a small amount of dry sherry added when served.

The “she-crab” was historically a gravid, or roe-carrying, female crab. Crab meat remains an important part of the soup, but it is the roe—not the meat alone—that distinguishes the traditional dish and explains its name.

Modern recipes sometimes omit roe or substitute other ingredients because of availability and regulations protecting egg-bearing female crabs. Those adaptations are still called she-crab soup, but the classic defining ingredient is crab roe.
