Mouth-Watering Duck Two Ways – Cooked
Sous Vide
Breasts and Leg
Confit
Difficulty: Gourmet (but worth it!)
Sous Vide Breasts: 135 degree F, 2 hr.
Sous Vide Duck Confit: 180 degree F, 12 hours
OK…I know
your first question: Why on earth is it important to cook
duck sous vide?
Duck breasts
are best served medium rare so make an ideal candidate for sous vide. By
cooking at 135 degree F for two hours much of the fat under the skin has
softened and rendered out while the proteins in it begin to set, making it easier
to crisp without shrinking on the stovetop just before serving. The result is
supremely tender, evenly cooked meat with super crisp skin, much better than
traditional cooking.
Duck confit
is made across France, and seen as a specialty of Gascony. The confit
is prepared in a centuries-old process of preservation that consists of salt curing
the piece of meat for 36 hours and then cooking it in its own fat. Once
esteemed as a preservation method, most people no longer have to keep duck
through the winter without refrigeration. Today, cooking and keeping the duck
in its rendered fat results in a meltingly tender, moist and extremely
flavorful meat that can be used in a variety of simple preparations. It just
happens to produce the one of the most wonderful delicious things on earth.
Unlike duck
breasts, duck legs are tough and need slow cooking to make them tender.
Confit is the traditional French preparation to cook the legs,
covered in duck fat to make them tender as well as preserve them. This requires
quite a bit of duck fat. But with sous
vide techniques you can get the same result with only a tablespoon of duck fat for
each leg. Duck fat can be purchased at D'Artagnan, Sur la Table, Williams-Sonoma and is often carried in grocers. If duck breasts are made in advance of duck confit, you can use the rendered fat from cooking the breasts later in confit preparation. Store duck fat in refrigerator or freezer. It is possible to cook duck legs at a lower temperature without fat
but it would not result in the traditional confit texture for shredding the
meat which requires cooking at 180 degree F. Prior to cooking, one must cure
the legs with a simple mix of salt and spices.
- 4 boneless duck breasts, 5-6 ounces each
- 4 duck legs
- 1 C Kosher salt
- 1 Tb dried thyme
- 6-8 whole black peppercorns
- 3 crumbled and 4 whole bay leaves (divided)
- 4 Tb duck fat
- Salt and freshly ground pepper for duck breasts
- Fresh thyme
- Grated orange zest
- Grated nutmeg
- Balsamic vinegar
- 2 Tb canola oil
To cook the
duck legs: crush the dried thyme and crumbled bay leaves in 1 C kosher
salt until it is evenly mixed. Add black
peppercorns. Sprinkle the salt mixture over the entirety of the duck legs.
Place in the refrigerator and let cure for 24 - 36 hours. I pack the cure as evenly as I can and vacuum
seal them to facilitate the curing process. If you do not have or wish to use a
vacuum sealer, just be certain to cover the legs entirely with salt mixture and
refrigerate.
Seal the curing legs in a seal-a-meal type bag |
Once cured, remove the
duck legs from the refrigerator and rinse thoroughly with cold water. Pat
completely dry with paper towels. Place duck leg, 1 Tb duck fat/leg in a large zipper lock or vacuum seal bag. Seal
using the water immersion technique or a vacuum sealer on the moist
setting. Place the bag in the 180-degree
water bath and set timer for 12 hours. Cover the water bath with plastic wrap
or sous vide balls to minimize evaporation and retain heat. Add water
intermittently to keep duck submerged.
When timer
goes off, remove the bag from the water bath. If serving immediately, remove
the duck from the bag. Heat a nonstick skillet or cast iron pan over
medium-high heat for 2 minutes. Add the duck legs, skin side down, and cook
until well browned, about 5 minutes. If
you are not serving immediately, leave the ducks sealed in the bag. Refrigerate
up to two weeks or freeze. The goal of duck leg confit is to have meat that falls
easily off the bone. In fact, one sign that the duck is done is that the meat
has pulled away on its own and revealed the leg bone.
To cook
duck breast sous vide: With the fatty skin-side up and using a sharp
knife, cut ¼ - ½ -inch crosshatch pattern in the skin of 4 duck breasts being careful not to pierce the meat. Do this while
the duck is cold, since its difficult to make precise cuts at room temperature.
Season the flesh
(meaty) side with salt & pepper,
grated orange zest, grated nutmeg, and a sprinkle of balsamic vinegar. Lay
a sprig of thyme running lengthwise
down the center of each breast and cover with one bay leaf. Refrigerate, uncovered, for at least one hour, or up to
12 hours.
Next, seal
duck breasts in vacuum or large zipper lock bags. Place in 135-degree water
bath for at least 1 hour and up to 4 hours. (2 hours is ideal as noted above)
Remove bags and dry thoroughly with paper towels. Heat non-stick frying pan over medium-low heat. Add 1-2 Tb canola oil. Set a metal bowl or other container near the stove. With a paper towel, blot any moisture from the duck breasts. Season both sides of each breast with a pinch of salt. Add the duck to the pan, skin-side-down. Move the duck breasts every few minutes to help them brown evenly. As the fat is rendered, carefully tilt pan remove the excess with a metal spoon (leaving about <1/8-inch) from the frying pan: Be careful to remove pan from the flame while doing so to avoid flare-up. Transfer fat to metal bowl. Flip and cook second side about 30 seconds.

white beans and sausage or pork belly
It is THE KEY ingredient in cassoulet from
Toulouse
Or, on their
own with a side of potatoes roasted in duck fat.
Duck breasts
are also wonderful on their own. Or, you could make a quick orange sauce for
Canard a l’Orange or follow one of my previous posts for duck breast.
