One thing I think would serve the community well here is a few choice cooking books for some of the great items sold here on Massdrop. Two items that come to mind are a cookbook for Dutch Oven cooking and a cookbook for Sous Vide cooking. Of course some blog posts to some great writers on the public webs would be a tremendous help as well. I know when I first started in this hobby I searched for books and while doing so found some great bloggers who had the same passion (in most cases even more enthusiasm than me hahaha). It was a tremendous benefit finding their sites and I would assume would help many others who are now buying cooking items online.
So for those of you who can recommend a dish (doesn't have to be the recipe itself as I would research the recipe online or in the public library) It would be a tremendous value to me.
Definitely bread making items in the cooking community would be a great addition as we near the beginning of seasonal holiday cooking (and who doesn't love bread!)
