Free yourself from recipes! The best-selling cookbook, Ratio: The Simple Codes Behind the Craft of Everyday Cooking, by me, Michael Ruhlman, is now an iPhone app that will help you calculate amounts of ingredients in all the fundamental culinary preparations. When you know a ratio, you don’t know a recipe, you know 1,000. And this application does all the calculating for you. “Cooking, like so many other creative endeavors is defined by relationships. For instance, knowing exactly how much flour to put into a loaf of bread isn’t nearly as useful as understanding the relationship between the flour and the water, or fat, or salt. That relationship is defined by a ‘ratio’ and having a ratio in hand is like having a secret decoder ring that frees you from the tyranny of recipes. ….Michael Ruhlman, in handing us mortals a power better suited to the gods, has changed the balance of kitchen power forever.” —Good Eats host Alton Brown What You Get: --THE 32 CRITICAL RATIOS that form the backbone of the culinary arts, with instructions: doughs, batters, meat preparations, custards, sauces (pasta dough and pizza dough, sponge cake and pancakes, fritters and crepes, stocks and sauces, crème caramel and chocolate sauce. --A CALCULATOR that figures out how much of each ingredient you need, no matter how many or how few people you want to serve. --An OUNCES-TO-GRAMS CONVERTER (ratios work no matter what unit you choose to use!). --DELICIOUS VARIATIONS FOR RECIPES on all the ratios, ideas for the creation of new dishes according to your tastes. --An easy way to STORE YOUR OWN RECIPES and notes that you’ve created from the basic ratios. --Quick fun ways to SHARE what your cooking with your fellow cooks, on Facebook and on Twitter. --Ratios is also a great way to understand and TWEAK YOUR OWN RECIPES, to help you make your pancakes even fluffier, your pizza dough crisper, your crème brulee richer.
