As resistant as I was to purchasing an iPhone and therefore joining the iPhone cult, I have to admit that I love, love, love that stupid thing. Someone told me when I bought it to prepare for a ridiculous level of love and passion for a simple piece of metal and plastic. They were right.
The iPhone is a window into the future. One day, everyone will have a similar device, and I imagine they will only get better and better.
The beauty of the iPhone, of course, over online devices, is in its size. I put it by my pillow where it wakes me up and puts me to bed. I have downloaded loads of free applications for reading all the classics I pretended to read in high school and college (so sue me; I skated through on my ability to write really convincing arguments based purely upon my assumptions of the stories). I frequently pass the hours playing Trivial Pursuit (against myself, where I always win), or the super easy level of Sudoku for kindergarteners. I listen to my various old school progressive rock radio stations on Pandora when sitting in coffee shops who play the greatest hits from the 80s you've never heard before but are guaranteed to make your ears bleed profusely, and when I'm bored I scroll through the featured apps and download things I'll never use and occasionally a gem or two.
I don't mind paying for apps because, like lots of people who provide lots of online content, I think it's okay to pay for it. ahem.
At any rate, I've known for awhile from Twitter that Ruhlman was working on a companion iPhone app to go with his fantastic book, Ratio. As a side note, can you believe I had both Charcuterie and Ratio in my car on the date that I met Ruhlman and it didn't occur to me to have him sign them? Oh well.
Ratio is the cookbook - or guidebook, rather - that I have been hoping to have for years now. There are loads of great cookbooks out there; there are even great cooking textbooks, such as the Professional Chef & Pastry Chef series. But even these books tell you mostly how to do things, specific things, rather than teaching you the foundational principles upon which they are built. Harold McGee's On Food & Cooking does a good job of teaching you the whys, but not the hows. Ratio brings the hows and the whys together in a very simple formulaic process.
Books like Ratio are important because once you learn the simple processes and ratios, you can free yourself from the bonds of recipes and learn to create your own masterpieces.
...where are we? Okay! So the Ratio app! It's $4.99. Considering how much we spend on cookbooks, it's a steal and a half.
The application is very well-designed. Upon entering the application, you are shown a screen which offers and introduction, the virtues of using a scale (I will admit to having a bit of a difference of opinion here, but then Ruhlman is the expert, and I am not - more on this in a bit), a little about the author, and how to use the application.
Under settings, rebels like me can choose to use volume measurements, versus the preferred measurements by weight. See? Even though the author doesn't agree with your choice, he still supports it! that is very nice of him.
Now we get to the ratios. There are seven divisions of ratios, going from doughs to dessert sauces. You click on the category you'd like, say, batters, and then you are presented with a screen for the different types of batter you'd like to make - poundcake, popovers, fritters, or crepes. Choose your pleasure and you will see the ratio. You can adjust the amounts for the number of servings you would like to have. For the visual learner, you can select to see a pretty pie chart of ingredients. Select "details" and you are provided directions to make the item and suggestions on making it better.
You can make notes for the item, things you've tried, additions or tricks you've learned doing it, and then you can name and save the recipe. To bring the whole thing full circle in our modern world, you can then email, tweet, or facebook the recipe!
The interface is simple and uncluttered; my favorite kind. Even better, it is incredibly intuitive. The more technology I use, the more I see intuitivity (yes I just made that word up) as being critical to the success of an application. This is probably why I love my iPhone so much. Now I would love to see someone create restaurant software which runs on a very intuitive interface. (I'd like a cut of that idea, if you invent one).
So far, my only complaint about Ratio is it doesn't allow me to type in landscape format.
I am super excited to test this out in actuality. Since I have used Ratio the book, the following (click through, because it's long and full of pictures) is a a pictogram of how I might have used the iPhone app to make stock (you can read about my usage of the Ruhlman stock method here and here, the second being the trotter stock):
