The 'M' Burger is one such example offered by McDonald's in the UK during recent months. A stone-baked Ciabatta style bun, 100% beef patty, tomato, Batavia lettuce, Emmental cheese slice and optional bacon with a 'delicious dressing'. The dressing seemed, at first taste, to be something close to a peppery mayonnaise. I can't say this for sure though as the testing was done purely on a review basis and so the more typical in-depth analysis and replication didn't take place for this burger.
Over the years, I've never been overly impressed with the limited edition items sold by most fast food restaurants. Tinkering for tinkering's sake is often the feeling i'm left with, particularly when it comes to trying to force a classic, traditional burger into something which could be classed as 'gourmet' by introducing unnecessary items such as ciabatta buns. A traditional burger bun is considered classic for a reason and so trying to turn it into something it's not often seems like a mutton dressed as lamb situation. Regardless, I have a keen interest in these things (had you noticed?) and so I decided to give it a go and see what all the fuss was about.
The ciabatta bun itself was surprisingly tasty. Of all the limited edition items I've tried, this bun was definitely the most impressive and I'd happily purchase it if it was available as a stand alone item from a bakery or deli. Call me a purist though (or just plain stubborn) but in this context it didn't cut it in comparison to the traditional and classic burger bun.
The Emmental cheese slice was pale and unattractive in colour but had a good, nutty flavour. As part of the Big Tasty (another limited edition menu item), I've definitely enjoyed it in the past. In the M Burger however, its flavour was lost somewhat, overshadowed by the flavour of the dressing and ultimately failing to combine in the successful way it does with the much loved Big Tasty sauce.
