I've hit a bit of a brick wall on this one, and was hoping the sages on here might be able to help me out.
I'm looking to source a quantity of beef bung/caps. The best price I've found for them is £2.50 each. I'll be using them to make haggis, so will get, I believe, 5 or 6 one pound haggi from each bung (anyone know if this is roughly correct?).
That makes them by far the most expensive ingredient in my haggis. I've been told that I can buy them 100 at a time for £2 each, but I'm not sure how long they store for and even then it still costs more than all the other ingredients put together. I can buy artificial skins for far less.
Secondly, does anyone know about, or have a link to, the tools used to make the metal crimps found at the end of haggis. Even a name for the piece of kit would be something. At the moment I'm tying with butchers string, but this is time consuming and difficult to get a good tight seal.
Any help would be hugely appreciated.
