A different kind of recipe for an old poultry - same idea (sort of
) :
Once in a while, throw one in a sceptic tank to keep the bacteria level high. [some say a dead one, others a live one
]
I take their word for it - I won't sample the result.
[ Who called me "lady" .... 
that's really a first. .... want more recipes like this one ? :D ]
