I have see the ladies in pigs twice at country shows this summer, and watched their cookery demo. Also they handed out little tubs of what they had cooked. I have never eaten curry, and have no wish to do so, but they assured all of us watching that we would like this dish, and it was lovely.
Was going to get the book, but there was such a queue for it, meant to go back and never did. Forgot about it till now, so will send for it!!
