Cooking Apps are all the rage these days. If you don’t own an iPhone or a computer (how are you reading this??!) you’re probably wondering: “What’s a cooking app?” Basically, it’s an application that you can download that aids you in your cooking. So there’s Michael Ruhlman’s wonderful Ratio app which calculates precisely how much butter and sugar you need if you have X amount of flour in order to make a batch of cookies. That’s really cool. And then there’s Mark Bittman’s “How To Cook Everything” app which Matt Armendariz writes about here. There’s also one from Epicurious, one from Martha Stewart and more and more cooking apps on the way now that the iPad’s here. But which one do I use most often in my kitchen? The answer may surprise you.
