Peppered Duck Breasts with Cherry-Port Sauce
Ever since figuring out how to get a fairly crisp-skinned, medium-rare duck breast on the the grill, they've become a more regular part of my grilling routine. This was a pretty big achievement for me, since previous failures kept me from investing in delicious duck breasts because I wasn't able to pull them off with results that I deemed acceptable. So now that duck is finding more favor at home, I'm always on the lookout of new ways to do it up, and this variation of peppered duck breasts with a cherry-port sauce is great compliment to the winter that has come early this year.
Something about sweet port feels so right when the cold starts to hit—that warming sweetness is comforting as the days grow short and frigid. So it seemed fitting that it served as the base of the sauce for these duck breasts. The port was paired with a natural tart contrast in the way of cherries and slowly simmered along with shallots, balsamic vinegar, and brown sugar until the sauce reduced by half and the cherries were completely soft.
With the sauce done, it was time to turn my sights on the main attraction—the duck. The best way I've found so far to get the right amount of fat and a crisp skin on the grill is to start by making some slits in the skin and into the fat of the duck. These slits will later allow ample space for the rendering fat to flow out of. The only other preparation these breasts got were the standard salting and an extra heavy coating of freshly ground black pepper.
Creating an escape route for the melting fat sounds like a great idea, but when it comes to actually grilling, it's a giant pain in the ass. Getting a good duck breast over a live fire is no easy feat. All that rendering fat hits the coals and causes constant flare-ups. Some excess heat is good—this is what helps the skin crisp—but too much will leave the skin a charred mess. So I kept a constant eye on the duck as it cooked, moving away from harms way when flames rose up. I did this until the skin had crisped to my liking, at which time enough fat had rendered out to leave only a pleasurable layer remaining.
Thanks to the high heat and all the flames, the crisping and rendering tends to happen quickly. It's so fast though that the meat rarely reaches the medium-rare temperature I'm shooting for by the time the skin is done. To get to my final ideal temperature of 130 degrees, I either flip the breasts and continue to cook over direct heat if I'm not too far off that number, or move the duck to the cool side of the grill, cover, and let it roast over indirect heat if I can tell it's going to take a while to finish up.
The effort put into cooking finicky duck breasts is well worth it though when you're rewarded with this—a medium-rare beast with a crisp skin and a thin, but luscious layer of fat. Grilling may not be the prettiest way to cook duck breasts, but the little added smokiness and slight char certainly give it a wonderful flavor that makes it unique.
I admit that even with a watchful eye, I may have let a piece of skin scorch here and there, but with the duck's thick peppery coating and that sweet and tart cherry-port sauce spooned on top, I didn't even notice in the end. The stress of cooking the breasts all faded when I began to eat and that juicy meat combined with the robust and fruity sauce, coming together into a rich and warm duo that was fitting for this cold start of winter.

- To make the sauce: Melt 1 tablespoon butter in a small saucepan over medium heat. When foaming subsides, add shallots and cook, stirring, until softened, about 4 minutes.

Set cooking grate in place, cover grill and allow to preheat for 5 minutes. Clean and oil the grilling grate. Place duck breasts on grill, skin side down, and cook until skin has browned and crisp, about 5 to 7 minutes. Flip and continue to cook until an instant read thermometer registers 130 degrees when inserted into middle of breasts. Remove duck from grill and let rest for 5 to 10 minutes.
- Slice breasts, spoon on cherry-port sauce, then serve.

Jim Watt Joshua,
Great blog with terrific information. We too really enjoy duck breasts done on the grill. Some of your duck fat dripping can be improved by rendering the breasts first. Sear the skin side, as I sw you had in your recipe, then place skin side down in a cold cast iron skillet then set to lowest heat possible & let the fat render out for ten minutes or so. the skin will begin to crisp, fat will be in the skillet, which is awesome for duck fat fried potatoes by the way, then let them cool before placing on the grill.
We've also been using a Traeger grill for the last year or so, at least when we're home (use standard grill when traveling). They're great since there is no flareups, plus you can use them for smoking a variety of items.
Keep up the great info.
