If you’ve had an egg salad sandwich in South Carolina—or pretty much anywhere in the southeastern U.S.—any time in the past 80 years or so, it’s a good bet it was made with Duke’s mayonnaise. Based in Greenville, S.C., the maker is owned by C. F. Sauer Co. Sales of Duke’s account for 3 percent of the total U.S. mayo market.
