Have in a pan water enough (a little more than blood warm) to come to the top of the mould. If the mould is tin, set it in this for about half a minute; if earthen, keep it in long enough to have the heat pass through the mould. Wipe the mould, place over it the dish into which the jelly is to be turned, and turn both dish and mould simultaneously. Let the mould rest a moment before lifting it gently from the jelly.
