GW2 Chef guides

Chef is probably the easiest crafting to max out, since many ingredients can be bought off of vendors instead of harvested or salvaged.

If you're just looking to level the chef crafting profession, this is the guide you want.

If you're just looking for cool things to make and don't want to just throw random things in the pot and see what sticks, there are two database sites and a google doc that list all the recipes. (Note that there are some which can only be crafted after buying a recipe from a karma vendor; those items usually have a quotation in their description.)

Also useful is the guide to ingredient locations.
