I just added Food 52 to my blog roll. I met with the founders of this site this past week. I really like what they are doing.
Food 52 is essentially a community of home cooks. You can submit your recipes or just comment. There are weekly contests for the recipe of the week which is becoming a cookbook. What I like more than anything is that Amanda and Merrill ( who is the smarts behind this site ) curate everything. They actually pick from the recipes that are submitted and make them. So the site isn't noisy. It is clean and precise. It is a bottom-up approach. Super smart.
Both Amanda and Merrill love food, are writers and get the new media world. There is also a shop on the site which only gives you the best of the best. A great tool.
Worth a daily check in. And if you are so inclined, submit a recipe or two.
