This document provides guidance on properly measuring ingredients for cooking and baking. It discusses different measuring tools including measuring glasses, cups, and spoons. For dry ingredients, it instructs to spoon the ingredient into the measuring cup without packing or shaking down and then level with a knife or spatula. Brown sugar is the exception and should be packed into the cup. Moist ingredients like butter should be packed into the measuring cup. Solid ingredients like raisins or nuts should be shaken in the cup to level. It also provides conversions for common measurements like teaspoons and tablespoons.
