I brine poultry.  1 cup pickling salt and 2 cups sugar per gallon of cold water.  Brine about 1 hour per lb.  Rinse well.  Because I use pickling salt (dissolves easily), I don't boil my brine.  I am curious if others add anything else to their brine.  I have found that herbs add no discernible flavor.  If someone has a different experience, I'd love to hear about it.
