Strainers and Sieves
A dumpling strainer is a tool for lifting a dumpling (particularly an Asian dumpling) out of the water it was simmered in.
A spider strainer is a low, shallow, round basket on a handle. It is called “spider” because it looks a bit like a metal spider web.
A tea ball is a small mesh or perforated enclosure designed to hold loose tea leaves while they are being steeped in hot water. The purpose is to provide a way to remove tea leaves all at once quickly and easily from brewed tea.
Tea strainers are small strainers used in the serving of tea made from loose dried tea leaves. The strainers are either designed to sit over the top of a tea cup, or be held there.
