What is a tea infuser?
A tea infuser is a small perforated basket-like container with a hinged opening. Loose tea is placed inside the infuser, which is then closed and lowered into the teapot filled with boiling water. The tiny holes in the infuser allow the water to interact with the tea leaves. A tiny chain with a hook at one end is attached to the top of the infuser. The hook slips over the rim of the teapot so the infuser can easily be removed. Tea infusers are usually made of stainless or chromed steel, although there are also porcelain and silver models.
