We use subtlehouse as a recipe book, and I have a recipe index on our intranet, with colored tagging for aspects that are relevant to us (can I make it when my arms hurt, will the household's picky eater eat it, is it veg*n, etc.). I took a screenshot of the index, since it's easier to show it than describe it.

Some of the links go to recipes on my personal journal (which are aggressively tagged, e.g., food.cooking.stew.beef barley), some to recipes on subtlehouse (which has a much less useful tagging system and I need to entirely overhaul it at some point), and some to web links (but I mostly copy recipes into my journal, with source links, so I can note modifications). It works pretty well.
