A tea infuser is a small device used to steep loose tea leaves in hot water. It allows the flavors and aromas of the tea to be released while keeping the leaves contained, making it easy to enjoy a fresh cup of tea without the mess. Infusers come in various shapes and sizes, including mesh balls, baskets, and even silicone designs. Using a tea infuser is simple. You fill it with your desired amount of loose tea, place it in a cup or teapot, and pour hot water over it. After a few minutes, you remove the infuser, leaving behind a flavorful brew. This method is popular among tea enthusiasts who prefer the quality of loose leaf tea over pre-packaged tea bags.
