Hey guys. I thought I'd share this with you as it seems to work quite well:
take 2 duck breasts, perforate the skin/fat about 20 places with a sharp knife.
rub with cracked rocksalt. Not loads, but you should know your own taste.
Preheat an oven to about gas mark 7/230 degrees, but here's the trick; Get your (clean) grill pan and fill it with about half an inch of hot water and pop into the oven.
The aim is to get the oven as steamy as possible to keep the duck moist and the skin crispy.
Now, heat a pan (I use the technique where if it's slightly uncomfortable to hold your hand about 2 inches above, it's good to go), and lay your duck skin side down. It should start to sizzle immediately.
I'll warn you here, there's a lot of fat, and it can cause a mess when is spits everywhere. Now's the time to use a splashguard! :)
Now you want to heat it one side for about 4 minutes until the skin is quite brown (I got it a little black first try, but as long as it's quite hard and crsipy, it's cool), then turn it over (only turn once!) and do the other side for about 4 minutes. I'f you check now, you'll still see a layer of fat underneath, and a little will end up rendered in the pan.
Now take your duck out, and put them in the oven, on the grill, skin side up for about 18 minutes. Try to resist getting them out early, but keep an eye out.
When they're done, all of the fat should have been released, infusing the meat (and unfortunately for those who value duck fat, into the water), and leaving the skin crispy.
I found mine to be perfectly pink (like a medium rare lamb steak) and a little rare in the middle with some blood (but still piping hot).
I believe duck is also classed as game meat rather than poultry, and doesn't need to be cooked in the same way as chicken, as they're often kept in better conditions, and their muscle fibers are packed too closely to let bacteria get inside the meat. However, I'm not qualified as a nutritionist or anything else, so use your own judgement, and enjoy wonderful low-fat duck :)
Oh and BTW, I've heard of similar techniques, but this is partly based on the way my friend told me he cooks peking duck.
