Gillian Polack is the current GUFF delegate and she is collecting recipes for a fannish cookbook. She says the following:
Foodie fandom: The all new e-cookbook
I collect good recipes from friends. I’ve discovered over the years that even fans who claim to be non-cooks often have one recipe, one mouth-wateringly wonderful dish that they make when asked to bring a plate. And fandom needs another cookbook. And I need to raise money for GUFF.
Send me your recipes! Ask your friends to send me their recipes! As many recipes as you like! Spread the word across world fandom!
