Mark Bittman’s How to Cook Everything is a mammoth cookbook filled with easy-to-follow recipes and interesting information about food and cooking techniques. The cookbook is now available in app form, and it’s just as handy-only much, much lighter. The app lets you browse 2,000 recipes and also features Bittman’s own picks. Users can vote on their favorite recipes, and the most popular ones appear in the app in a featured recipes section. If you want to search through the recipes, you can do so by cooking term, ingredient, technique, flavor and recipe type. All recipes are marked by their type: fast, make-ahead, vegetarian and essential. (I’m a fast- and make-ahead-recipe person myself.) When you are reading the recipes, you’ll be given an overview, a list of ingredients and the steps to follow. Many recipes also feature variations so you can spice things up if you like. Recipes can be saved to a favorites list or added directly to a shopping list. This list can be sorted alphabetically or by aisle, which is a great extra feature in a cooking app. And as you find great recipes, you can share them on Facebook and Twitter directly from the app. How to Cook Everything is a great all-around cooking resource and a must-have for my iPhone.
