WP Ultimate Recipe - I used to pan recipe & food activities on the computer & online (yawn) ... but have recently seen the light. This venue does have various kinds of useful legs. During my survey of the scene, though, I noticed several factors to bear in mind.

1.) Common Standards & Formats. Interchangeability. Export/Import capability. Hey ... type 'recipe' into the WordPress plugin-search, and behold - 81 titles. And there are interesting differences among them. You don't want to laboriously type-in your recipes, only to have all that work locked-in (that's a naughty word, people) to any one plugin. In fact, you largely don't want to be laboriously typing-in, period ... you mostly want to import at least the bones of standard recipes, and then maybe edit to personalize or specialize.

2.) Nutrient-integration. Meal-collation. Shopping-list. Recipes can be collated into meals (and weekly & monthly plans), which can be integrated with the famous USDA Food Nutrients Database to show you the nutrient composition of food-items, meals, and entire ongoing dietary regimes. Want to go on a low-carb diet? Getting guff from the Doc about glycemic sensitivity? Did you join the local Mixed Martial Arts MMA gym, and aim to be a lean, mean fighting-machine?

Then after you've picked the weight-class you should be able to drop down to, and the BMI you think you can achieve, and have laid out the meal-plans that will get you there ... the right recipe program can build the shopping-lists that will keep your home pantry stocked with all the ingredients needed to prepare the meals that take you there.

3.) Notice that once we have good Import/Export capabilities, it then becomes attractive for plugins to increasingly specialize ... and to thus become smaller & simpler in their mission & coding ... and thus to be more suitable to the plugin-game. Common formats & interchangeability of recipe data & content create a virtuous-circle of plugin enhancement & promotion.
