oooh noo noo! Don't waste them..
I cook mine in the oven, with an inch or so of water in the bottom of the tin,
you can cover with a bit of butter, lemon, garlic if you wish,
cover with a tent of foil, making sure you seal all around so no dry heat gets in, then roast/steam in a medium oven for a couple of hours.
Take the foil off for the last 20 mins or so to crisp the skin.
Succulent and delicious, even the older ones come out moist and tasty
