I believe the filling was jaggery and coconut, yes, although the only word I recall clearly from Kazi’s description was “jaggery.”
We’d actually crossed the street to check out a different cart that offers pati shapta, then ultimately bought one from Kazi (on the sidewalk) and his partner. Their menu features at least a half-dozen varieties of pitha, including bhapa, chitoi, teler, nakshi, puli, and vapa puli pitha. Haat Bazaar, we later noticed, now displays pati shapta near the register, too.
