MacGourmet

MacGourmet is a recipe organizer for the Mac that bills itself as iTunes for recipes. In their own words:

MacGourmet helps you create and edit recipes, wine notes and cooking notes, easily browse your entire collection and build your own custom lists for categories like appetizers or desserts.

The interface is pretty slick, and I especially like the Chef View, which blows up all the text so you can more easily read the recipe while keeping the computer away from the cooking area.

While you can publish recipes to the web using .Mac, it would also be neat to see some kind of interactive social networking implementation—maybe other MacGourmet users could rate the recipes you publish—or some other Web 2.0-ish stuff: plug a MacGourmet recipe into an online grocery and automatically buy everything needed for the recipe with a single click (a la Amazon.com).
