Big Mac - move over, Filet o Fish - you're off the hook.

McDonald's is launching a new addition to its Irish menu: the McMór, which will feature Ballymaloe Relish and Charleville Cheddar.

The McMór will be available in all 88 McDonald's restaurants across Ireland from Wednesday September 2nd for a six week period.

McDonald's says the burger is a "tribute to the best produce and finest flavours from across Ireland".

The McMór was created by McDonald's Ireland Chefs Council, which held its first meeting in May 2014, with the view to developing an authentic local burger with Irish flavours.

Speaking about the launch, marketing director of McDonald's Ireland Roma O'Connor said: "We're delighted to launch the McMór - and to be collaborating with great Irish producers to create our first ever Irish artisan burger".

"I'm confident that customers will love the taste of the product and the Chefs Council has been working hard to ensure just the right mix of ingredients to deliver an authentic Irish taste...in fact a real taste of home".

Commenting on Ballymaloe Relish's agreement with McDonald's, Maxine Hyde, marketing manager at Ballymaloe Foods said: "When we were approached by McDonald’s Ireland in the development of the McMór, we quickly agreed to participate in the project. We have been working with the development team ever since".
