Each year in December food blogger Pim Techamuanvivit (Chez Pim) organizes the Menu for Hope to raise funds for a food charity. Techamuanvivit has just put out a call for participation for this year's Menu for Hope VI, taking place December 14–25.
The skinny: Food bloggers offer a raffle prize that their readers then buy tickets for. Prizes can get pretty crazy and special—food tours, food-related classes, small appliances, dinners cooked by hotshot chefs, etc. (here's last year's master list).
