Orange Marmalade
Rasp the oranges, cut out the pulp, then boil the rinds very tender, and beat fine in a marble mortar. Boil three pounds of loaf sugar in a pint of water, skim it, and add a pound of the rind; boil fast till the syrup is very thick, but stir it carefully; then put a pint of the pulp and juice, the seeds having been removed, and a pint of apple liquor; boil all gently until well jellied, which it will be in about half an hour. Put it into small pots.
Lemon marmalade do in the same way.
