After a revamp of its iconic Big Mac, McDonald’s is trialling a new flavour of french fries.

Dubbed “Gilroy Garlic Fries”, the new fries are seasoned with garlic grown in Gilroy, California – the “garlic capital of the world”, McDonald’s said.

The fries are also made with olive oil, parmesan cheese, parsley and a pinch of salt.

Garlic fries are available in four restaurants in San Francisco. If successful, the trial could spread to 250 McDonald's restaurants in California this August.

The garlic fries are part of McDonald's efforts to experiment with regional flavours and food on its menu.

Chef Michael Haracz, manager of mulinary innovation at McDonald's USA, said the company is committed to listening to their customers.

“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,“ Haracz said.

Fast food giants fans took it to Twitter to talk about the latest menu addition.

It is unclear if there are plans to introduce the item in UK restaurants.

Garlic fries are the latest new addition in a long line of new McDonald’s products.

The company is also testing out smaller and larger Big Macs in Texas and Ohio restaurants and all-you-can-eat fries in Ohio and Dallas.

In Korea, franchises started to serve alcohol. In Hong Kong, restaurant owners installed futuristic interiors and sold salads and other healthier items.

But it’s McDonald's All Day Breakfast, launched in October last year, that has proved most popular.

Analysts said that all-day breakfasts have attracted customers back to McDonald's stores and increased sales of non-breakfast items.

McDonald's reported that sales at restaurants open for at least 13 months had risen 5.4 per cent in the first quarter of the year, beating analysts’ expectations of a 4.6 per cent rise.

“While there is still work to be done, we are on the right path to make even greater progress. I am confident that our continued efforts will deliver meaningful long-term value for all stakeholders into the future,” said Steve Easterbrook, McDonald's chief executive.
