One of the standout features of glass measuring cups is their clarity. Unlike plastic counterparts, glass measuring cups do not easily stain or absorb odors, allowing for a pure view of the contents. When measuring liquids, it is crucial to have an accurate read on the amount — a high-quality glass cup offers not only marked measurements but also the ability to see the meniscus, the curved surface of the liquid, for precise gauging. This clarity is particularly beneficial when measuring ingredients like water, milk, or broth, where accuracy can impact the outcome of the dish.
