I have a couple who are wanting to get a double boiler with their new executive cookware set, which they have put on their wedding registry. I noticed that the double boiler is being discontinued, though! Does anyone know if there are plans to make one for the executive line, or if the current one will fit the executive cookware as well? It says it will fit the professional and generation II, but I'd hate to tell them to go ahead and order it now, and then have it not fit their new cookware.
