Good:

• Includes calendar and daily/weekly meal planning
• Shopping list with option to combine ingredients and export to iPod

Bad:

• Would be good to see daily/weekly recipes without filtering out all other recipes
• No automated filtering or classification of recipes by meal, ingredients, etc (only manual sets)
• No automatic serve scaling
• Application crashed once after testing

If meal planning is more important to you than recipe management, it would be hard to go past this program. The interface takes a little getting used to, but the calendar based planning feature is a winner if you can work with it. If however, you just want a program for managing your recipes, I would probably rate Connoisseur and A Cook's Books higher, but only just and for different reasons: Connoisseur is less feature rich but has the most user-friendly interface, and A Cook's Books has the most features. Shop'NCook is another good option if a nutritional database is important to you.

The programs I tested, roughly in order of preference were:

1. Connoisseur 1.1.7 (great interface)
2. A Cook's Books 0.9.19 (feature rich)
3. Shop'NCook 3.1 (includes nutritional database)
4. Organized Gourmet 1.2 (calendar based meal planning)
5. MacGourmet 1.1.7 (attractive interface, includes wine notes)
6. iCuistot 1.1.1 (includes nutritional database — sort of)
7. Kitchen 1.0 (simple interface)
8. Yum 0.7.8 (simple recipe manager)
9. Measuring Cup 1.1.1 (simple interface)
10. CookWare Deluxe 2.1 (includes a very basic meal planner)
11. The Computer Cookbook 3.1

Note: There are many others that I didn't test at all because they looked less promising, based on their descriptions and other people's reviews. There is one commercial product (TheRecipeManager) I refuse to test because of the developer's crazy policy of buy before you try. While I have tried to give a fair and honest appraisal of each product, I don't pretend that each review is exhaustive or totally without error. If I have overlooked any feature, it's possibly an indication that the feature was difficult to find or unintuitive to use — so in any case the reviews are a valid record of my opinion and individual experience.
