McDonald's is testing a new menu item, and it's a twist on a classic.

For a limited time, McDonald's is cooking its Quarter Pounder burgers with fresh beef, but only in 14 restaurants around the Dallas-Fort Worth area in Texas. McD's usually flash freezes its burgers.

"Like all of our tests, this one too is designed to see what works and what doesn't within our restaurants by considering the operational experience, consumer response, price points and other important information which may inform future decisions," a spokeswoman from McDonald's told CNBC.
