I did exactly the same thing this time last year Pasta. I thought I'd try some haggis as they were doing it at my works canteen, but I didn't like it. I'm glad I tried it though. I'm always up for trying different foods.
When I was dithering over whether or not to buy it,I asked a lady next to me. She said it was 'like really tasty mince...but better'. She was right.
I got mine from M&S...made by Macsweens who are said to be one of the best.
