Did some digging on the location where this alleged spirit cooking event occurred. Once a year during the summer The Watermill Center, located near the Hamptons in NY, holds its fundraising extravaganza inviting celebrities and wealthy donors to attend.
This article shows a few art displays for this event from last year:

All these photos are nothing more than performance art. The center is into very weird art probably because most wealthy there or visiting there are as well. Displays vary each year for the annual fundraiser and are tailored to the celebs they invite to perform.
