I think I might have that book....although I haven't looked at it for a fair while and have lent it out to another member here right now.
If it's not that one then it's one just like it I have......I'm sure AndyN will be along shortly and as he "still"
has my copy he can tell you what he thinks of it.
From memory it does have some pretty useful stuff in it about drying foods and so on.
Sorry I can't help more...the old grey matter seems to be letting me down!
Cheers,
Bam.
