Installation of RecipeBook (RP hereafter) was easy and involved a small 29.5 MB download. My first observation was that RB was fairly snappy on my aging TiBook 667 MHz. I was a bit surprised by the OS requirement - RB seems like a relatively simple database software concept that should require an OS less strenuous. (I say that because I was using Panther and had to buy an upgrade to Tiger to perform my evaluation.) The left side of the window has a pane where the default recipe books reside, as well as My Recipe Books — books that you can create to group recipes by "subject", like creating playlists in iTunes. There are no pre-sortings by category for the included recipes, i.e. chicken, appetizer, birthday, etc. You can drag 'n' drop recipes from the right into your books on the left. They are listed alphabetically and you can add as many as you like. (The recipe books are listed alphabetically and you cannot rearrange them. And it is also possible to create two books with the same name.) The bottom left has some nice search options. You can search by word, however it is not a live search — you must finish typing and click Go — and it only finds words in recipe titles. There are no keywords to search on or search the notes section. You can also search by rating, by servings, or by prep time. The default view on the right side is a List view which includes a nice photo of each dish (you can add a photo for your own added recipes,) the preparation time, servings per recipe and calorie count. RB comes with a ton of recipes pre-loaded, I didn't count how many and there are no stats of how many records are in the database. (Some folks might like to know.) Later I discovered Column view, which also included ratings, and a nice, responsive mouseover feature. All recipes are presented alphabetically; there is no way to re-order them. I found no way to add ratings to my recipes, or to change ratings of included recipes. (I would suggest to CalorieKing that the new "album view" in iTunes and the upcoming Leopard OS would look GORGEOUS in RB!) The button to switch views had a muted appearance and I overlooked it until deep into my eval. Double clicking on a recipe opens the recipe into a full page view, complete with picture, ingredients, steps, notes and nutritional information. Amounts are given scientifically, i.e. .333 cups honey instead of 1/3 cup. You can use metric units if you wish. All the provided recipes are easy to follow; all seem fairly rudimentary skillwise. Probably most importantly, all the pre-included recipes seem to be of a healthy nature, modern, and I'm sure they will appeal universally. The pages may be printed 8x10 and they too look GORGEOUS — ready to assemble into a ring binder homemade cookbook. I found I had to reduce the scale in Page Setup to get all the information to print on my Epson C84. Adding a new recipe is easy. I usually dread using recipe software because of the tedium involved of typing amounts and tabbing through fields. RB is different. Click New Recipe at the bottom of the main window, click each field to enter info. For the ingredients section you click in the field and you get a drop down menu that allows you to pick from hundreds of pre-selected and evaluated items. The one big disappointment I found is that after reading that ingredients marked with an "i" will automatically provide nutritional info. At the end of my recipe creation for muesli I clicked "Estimate." A note popped up saying *all* of my (simple) ingredients were unavailable for info!!! Apples, oatmeal, walnuts, and soy yogurt! Back in the dark ages, in college, I had to thumb thorugh nutritional indices for hours to get the bare minimum of info that RB provides in abundance in only a few minutes! So this feature shows much promise once I can get it to function. I also couldn't find a way to give my recipes ratings, nor could I change ratings of the provided recipes. Very importantly, all the recipes can be "scaled up" or "scaled down" to accomodate the number of diners to share in the food. Unfortunately, the scaling is done scientifically. There are not a whole lot of menus in RB, only the app menu, File and Help (interesting thing here is there is no Help command or function! There's not even a Command+P to print!!! Copy & Paste commands still seems to work, though...) I'd say obviously CalorieKing is trying really hard to "keep it stupidly simple," so I have no great complaint about that fact. In that vein, there is no manual available either. There are no contextual menus either — I could probably dream up some reasons to include that feature (i.e. there is no way to duplicate a recipe that you could then modify to create a completely new dish. A simple pop-up "Duplicate Recipe" would be awesome.) While you can edit your own recipe creations, you can not modify RB-supplied recipes. Copyright protection, perhaps? It would also be nice to be able to share your recipes, a la Web 2.0, or export them as an HTML template. I give the software a solid 4 rating, mebbe four and a half once it matures a bit in later versions. I once had a customer during my in-home sales day a few years back who took the time to show me a recipe book that he not only created, including pictures, but refined with great pride. RecipeBook would have been a very welcome tool to accomplish his task. So I highly recommend it to all who are active in maintaining a computer-based recipe file.
