What on earth are chardonnay-flavoured crisps from Yorkshire doing in Catalonia?
It doesn't take much to destroy a myth: just a bizarre object in an equally unlikely setting. Let's do that setting first. One of my favourite shops in all the world nestles under a sandstone arch in the small walled village of Ullastret, 20 miles from Girona in Spain. Basically, it's a butcher's. The meat grows fat in the fields at the back: from sty to sausage in two easy stages. But, since this is the only shop around, they do bread, veg and sundry staffs of rural life as well.
