What's the best strategy for finding things on EpicureanFriends.com? Here's a suggested search strategy:

  • First, familiarize yourself with the list of forums. The best way to find threads related to a particular topic is to look in the relevant forum.

  • Use the "Tag" facility, starting with the "Key Tags By Topic" in the right hand navigation pane, or using the "Search By Tag" page, or the "Tag Overview" page which contains a list of all tags alphabetically. We curate the available tags to keep them to a manageable number that is descriptive of frequently-searched topics.
