Imitation Black Forest Hams are made in North America.
They have no rind, and because they are cured with brine, inside they look like a regular brine-cured ham. They may be smoked or smoke-flavoured. The outside is coloured with caramel. In Canada, processors got permission in March 1999 to use iron oxide instead of caramel. This allows “an easier and more economical production of the traditional black coating on black forest ham” (Canada Gazette. Vol. 133, No. 5 — 3 March 1999.)[quote/]
