Well known for its signature fries, McDonald's is testing out a new spin on them, made with sweet potatoes.
Some 18 restaurants in the Amarillo, Texas, area are selling the new fries.
Prices vary by restaurant. On average, they are selling for $2.49 for a 16-ounce size.
"Considering the fries are a test, they will be offered for a limited time as we gather feedback from our customers," said McDonald's spokeswoman Jeanette DeBartolo. "There is currently no plan to launch them nationally."
