'Old Faithful' - Black iron frying pan.
I bought my 'Black Iron' frying pan ages ago, and its probably the one single item of cookware that goes out into the field with me more often than any other piece, in fact I would go so far as to say that it never gets left behind. Its like an old friend, it has a huge amount of sentimental value, it has fed countless numbers of people with bacon sarnies, and cooking up my favourite mushrooms on more occasions than I could possibly remember!
