The blog 'Our Libatious Nature' says they can see why this cocktail has remained forgotten, the signature cocktail of the Chatham Hotel in NYC, long gone, between E 48th & E 49th, facing Lexington Avenue. My version, tonight, was more like a Motel 6. I used brandy instead of cognac, marsala instead of port, homemade creme de cacao & perhaps the biggest downfall, yoghurt instead of cream (I was working with what we had). It was a strange pink colour & not quite right tho that was probs my fault.
