A 19th-century cookbook gives new twist to 'soul food'

For nearly seven years, Jan Longone, an antiquarian cookbook collector, has been haunted by a ghost. The spirit came into her life as thousands of other vintage volumes from book dealers had before: in a plain brown wrapper. But as soon as she held Malinda Russell's "Domestic Cook Book: Containing a Careful Selection of Useful Receipts for the Kitchen," she could see its author and her world - the small, seldom-discussed society of free blacks in the 19th century - coming to life before her eyes.
