Another day, another product McDonald’s is throwing out there to see if it’ll stick: this time it’s garlic fries made with locally-sourced garlic.

Four San Francisco restaurants will be selling “Gilroy Garlic Fries,” made to order fries tossed with a puree mix of garlic, olive oil, Parmesan cheese, parsley, and salt, the company announced. The garlic will come from Gilroy, CA, “the Garlic Capital of the World,” which is about 80 miles south of San Francisco.

If this small test proves successful, McDonald’s will make the specialty fries available in around 250 restaurants throughout the San Francisco Bay Area.

“McDonald’s is committed to listening to our customers as seen by All Day Breakfast,” Michael Haracz, manager of culinary innovation at McDonald’s USA, said in a statement. “We’re proud of the work done by local franchisees and the regional team to create this menu item with locally-sourced garlic and we look forward to introducing Gilroy Garlic Fries to our customers in the Bay Area.”

It seems unlikely that the menu option will go national, considering the emphasis McDonald’s is placing on the local ingredients in this instance. Other regional tests the Golden Arches has tried include burgers with bourbon sauce in Kentucky and lobster rolls in New England, Nation’s Restaurant News points out, products that you won’t find on your local menu elsewhere in the country.
