Well, its in the Nigella feast book (spiced and super juicy roast turkey) and sounded great! I am all for damage limitation.
In a bucket or largest cooking pot you put 6 litres of water, 375g salt, peppercorns, bouquet garni, mustard seeds, 200g caster sugar, 2 onions, ginger root, cinnamon stick, cloves, allspice berries, star anise, 1 orange (mushed) 4 tblsp syrup and 4 honey and parsley.
You can add whatever spices you like the main thing is the salt and sugar.
Then you chuck the turkey in and let it bathe.
Take out Christmas morning, pat dry then brush with melted maple syrup and butter.
I shall get back to you and let you know if it works!
