I've found the site
taste.com.au really useful recently. It's well designed and they seem to have thought of it all...

Not only does it aggregate recipes from a whole load of different recipe/food sites, but also:
- Recipe reviews by users
- news
- cooking tips
- info about ingredients
- info about specific cuisine types
- forums to chat to other foodies
- member login where you can save recipes you like, add your own recipes to your 'folder', save a recipes ingredients to build a shopping list
- Recommends similar / related recipes
Certain recipes are grouped to make it easier to browse for specific types like collections of side dishes, turkish food... I particularly enjoyed looking through the
barbecue collection and am planning to try the prawn skewers this weekend - yum!

I also looked at
cuisine.com.au, I prefer the more subtle look and feel and its groupings and search are simpler and make a bit more sense, but doesn't have the same level of functionality with the member login, user reviews and forums which Taste has.

Love the wine matching tool though!
