It's not a f***ing burrito; Mexicans wouldn't recognise it as such. It's just a roast dinner, wrapped inside a Yorkshire pudding. It's just a pile of nonsense.
I just looked up the history of the term and whilst we commonly know the burrito as a flour based tortilla the term seems be derived from its appearance as opposed to its ingredients or other. In some parts of Mexico its called a flauta (or flute) which backs this up. My point being is [MENTION=5200]Buzzer[/MENTION]'s item can be referred to as a burrito....albeit a British one.
I actually like this sort of "nonsense" i.e. the messing and mixing and evolution of food cultures. I'm a huge fan of the balti pie which to me is the ultimate post-modern culinary response to multicultural Britain. This is the same.
