While many kitchens stock plastic measuring cups, glass measuring cups have distinct advantages. Glass is non-porous, which means it won’t absorb odors or stains from ingredients like garlic, vinegar, or food coloring. This non-reactivity ensures that your ingredients retain their flavor and integrity. Additionally, glass can be safely used in the microwave or even in the oven, allowing you to melt butter or heat liquid without the fear of melting plastic.
