If you're in New York, know that Now, Forager - A Story About Love & Fungi shows today at the IFC Center in Manhattan. It's about mushrooms and foraging and cooking and love. The story follows a couple who forage for a living. It is painted as a fairly grim existence; early in the film they buy $3 and change worth of gas - it's all the cash they have - on their way to sell the mushrooms they've foraged in the woods to restaurants in Manhattan).
I learned that the relationship between fungi and what they grow on - and, one images, between people as well - can be mutually beneficial or parasitic, and that "sometimes you can tell the relationship at a distance, sometimes you never know."
I know what is true, though, for all the fancy restaurant dishes seen and described through the course of the story, I doubt anything could possibly taste better than the dish of fresh picked morels, a wild egg, and ramps one of the characters cooks himself while out in the woods on a foraging trip.
