Have you ever watched Chopped on the Food Network? 4 chefs are given a basket of ingredients and expected to transform them into either an appetizer, an entree, or a dessert within a time limit. Now think about informational text writing. Basically, it's taking a group of facts and transforming them into a book that people will want to read. You have text features that you use to make your book appealing. Kind of like adding spices to your dish. Or not, if you don't like this analogy.
