Claim: Smart-Grosvenor released cookbooks about Vibration Cooking which is a method of cooking that raises awareness about the Gullah culture, which are African Americans from the Low-country region of the U.S., who created the creole language.
Evidence: The recipes pay homage to Grosvenor's own cultural roots in Geechee (or Gullah) culture and Lowcountry cuisine. The Gullah (/ˈɡʌlə/) are African Americans who live in the Lowcountry region of the U.S. states of Georgia, Florida, and South Carolina, in both the coastal plain and the Sea Islands. They developed a creole language, also called Gullah, and a culture with some African influence. Grosvenor is the author of several books on African-American cooking, but is perhaps most famous for Vibration Cooking: or, the Travel Notes of a Geechee Girl (1970), an autobiographical cookbook and memoir.
