Tea Ball-Stainless Steel. This mesh tea ball is great for a cup or small tea pot and gives you the option of blending and making your own teas, including herbal teas. (See our list of herbal teas under “Recipes.”) The mesh tea balls do darken over time but this is from the tannins in regular tea. They’re not a problem so just let your tea ball darken. You can also use the tea ball to hold spices for mulled cider or wine. Just open it and use half of it like a small strainer, too, if you want. Comes in various sizes.
