A tea cosy traps a layer of air around the pot, so the second and third cups are still hot. It matters most for ceramic pots and for a long afternoon tea.

Getting the fit right

  1. Measure the height of your teapot including the lid knob.
  2. Measure the width from the tip of the spout to the back of the handle.
  3. Compare with the cosy's listed size. It should go on and off easily, with openings for the spout and handle or a loose fit that covers them.

Cosies are often sold by pot size (for example 2-cup, 4-cup or 6-cup), but teapot shapes vary, so measurements are safer.

Also useful

A cosy suits a round, squat teapot best. For a full table, see how to host afternoon tea.
