Do you know the difference between a yam and a sweetpotato?
“A true yam is not grown in the U.S., it's found in South America,” says Jason Tucker, vice president of the California Sweetpotato Council. Real yams have dry, dark flesh and are not the same plant species as sweetpotatoes, he explained.
“A yam is a sweetpotato, at least for those grown in the U.S.”, says Scott Stoddard, UC Cooperative Extension advisor in Merced County. “The rest of country has predominately just one type of sweetpotato, with tan skin and orange flesh, but in California, we have four marketing classes.”
The four kinds of California sweetpotatoes are
- Jewell, with tan skin and orange flesh
- Jersey, with light yellow skin and white flesh
- Oriental, with purple skin and white flesh
- Garnet, with red skin and deep orange flesh
The red-skinned sweetpotatoes are what many people in the United States call yams.
The California Sweetpotato Council spells sweetpotato as one word because it isn't a potato, it is a different plant species.
