I love this idea` from French Women Don't Get Fat,not that I'm implying anything.
It's very simple but delicious and if you don't have any of the ingredients you can improvise or miss one out.
Put sa pinch of coarse salt,crumbled bay leaves,dried thyme,parsley, 2 garlic ccloves,peeled and sliced, 1/2 teaspoon shallor, black pepper, coarse is best into a baking pan and roll the duck breasts in the mixture.
Once both sides are thoroughly coated, cover with clingfilm and put in the fridge, skin side down. Leave it to marinate for 24 hours, or as close to as possible, turning once.
Then wipe or rinse to remove excess marinade, though I like to leave a little on.
You can then grill for 2-3 minutes skin side down, turn then grill again for 3-4 minutes, longer if you don't like it medium rare.
I prefer to fry it skin side down though, no fat is required to do so as the breasts fry in their own fat.
It's simple but delicious. I usually have it with sauteed potatoes and roasted asparagus.
