The only time I was at a con, they had some "Romulan ale" they mixed up in the bathtub. It was swill, but when I tasted it, it was swell swill. My late High Priestess' partner was a Big Name in New York fandom. But he just made homemade beer, and I don't like beer. I have an old fannish cookbook, and a Next Gen Trek cookbook. And I occasionally make something up. And "astronaut" freeze-dried raspberries have quite a few out-of-this-world uses.
