Any food and Apple lovers out there must use MacGourmet to organize your recipes. I've been using it for a little over a year now and absolutely love it. Anytime I find a good recipe that I want to keep, I add it to my MacGourmet so I won't chance throwing the recipe card away.
It's also very easy to "drag and drop" recipes you find online into your MacGourmet recipe box. Give it a try! There are many more features to this program, such as easily creating shopping lists from the recipes you choose, organizing menus, rating your recipes, etc.
