Baking refers to cooking food in a sealed enclosure, traditionally done underground or in ovens. Baked goods are generally healthier than fried foods as they contain less fat. Proper baking times and temperatures are needed to produce foods that are moist and flavorful rather than dry or hard. Common baking equipment includes various pans, bowls, spatulas, whisks, and thermometers. Measurements of ingredients should be accurate, using scales, measuring cups and spoons. An oven provides an enclosed space to bake foods through heating by electricity or gas. A sample brownies recipe is provided demonstrating the process of melting and mixing ingredients, baking, and cooling the baked goods.
