Do a Google search for "hardy orange marmalade" - you will get a number of
recipes, a few of which I have tried.  The best product was an orange
marmalade that used frozen orange concentrate (with pulp) and boiled thin
strips of poncirus trifoliata - that way you can just peel a thin layer off
the hardy orange and not have to deal with the sticky sap in the inner
peel.
