Well, thanks for all those brilliant (and frankly weird) suggestions. I’ll be posting a list, with full attributions, soon. In the meantime, I did think of another one. And here it is:
Pastis – that potent and aromatic aperitif, redolent of lazy afternoons in the baking sun of southern France
pasties – Cornwall’s finest, saturated-fat laden gourmet treat, redolent of days spent shuffling round the Eden Project, paying through the nose for parking and amusement arcades where your shoes stick to the carpet.
