Thanks all, (and thanks for that link, Molly, which mentions they get served at rugby / soccer matches). Certainly looks very nice as a winter warmer!
I was wondering what they serve stovies in at these games - presumably polystyrene containers with a plastic fork ..... down here, they rarely stray beyond burgers and chips at my local grounds, although Barwell FC do a gorgeous chicken curry for £3.50 and Tividale FC have been known to sell hot slabs of bread puddin' for 50p ... I think I spent more time at the hatch the day I went there than watching the match!
