Thanks for all the advice. I think I may try a Caerphilly as my husband likes it although it is a little bland for my taste.
I am currently using only milk very local to our village and although it is homogenised and pastuerised, I find calcium choloride seems to deal with any problems. To my delight I have discovered a source of natural spring water in the locality which I shall be using in future. Up until now I have been buying bottled spring water which although cheap enough, rather negates my principle of using really local resources.
I live in Cornwall in the South West of the UK and am surrounded by villages with the strangest of names. Amongst them are Water-Ma-Trout, Goon Gumpas, Playing Place, Mousehole, Indian Queens, Little Beside, Praze-an-Beeble, Knave Go by.
Knave Go By is where the spring or shute is http://www.facebook.com/photo.php?v=541806289176863
