Answer: A cushaw is loosely defined as any of several types of crookneck winter squash. Folks in the Appalachias tend to lump things together - I know, I live in the heart of the Appalachias now! I believe you are looking for the type that is marketed specifically as Cushaw Squash. This is currently available from Seeds Blum at http://www.seedsblum.com/squash.htm. The one they carry has a green striped exterior though, not white. Were you referring to the flesh of the squash being white? The one offered by SeedsBlum is described as "good for pie" so I am betting it's the one!
