Measuring cups come in varying size and materials in which they are made up of. They are made up of wooden, glass, stainless steel or ceramic material. Mainly these cups come in two different types.
Measuring cup for Dry ingredients: It usually comes in varying size of 1/4-, 1/3-, 1/2- and 1-cup measurements.
The simplest way to measure these ingredients is to scoop up whatever you want such that it overflows from the cup. Now take a knife and scrape off from the rim so that the excess thing just falls off. Mostly it is used to measure things such as flour, sugar, pulses, etc.
Measuring cup for Liquid ingredients: It has a good handle so that you can easily pour off the ingredients. Most of these are made up of either glass or plastic material so that you can easily see things through it. It usually comes in varying size of 1-, 2- and 4-cup measurements (and up). So as to get the exact measurements, place them on a leveled surface.
