This was served as part of the third course at the Ymir 2025 feast, plated on top of barley cooked in duck stock.
What, Where, When
- Duck served in two preparations from a single bird: seared breasts, and beer-braised legs pulled from the bone. Served together on a bed of barley cooked in duck stock, garnished with sautéed mushrooms and crisped skin ribbons.
- A conjectural Viking-age dish. Ducks — domesticated and wild — appear in Norse archaeological finds; method is modern.
Discussion
Viking-age archaeological sites in Scandinavia include remains of both domesticated and wild ducks, and contemporary overviews of Norse foodways list ducks among the meat sources routinely consumed. The typical period treatment of fowl was a slow stew with vegetables and herbs cooked over a fire, which the beer-braised legs below are similar to in method and outcome, if not in specific ingredients. The reasonable range of period cooking methods for duck is narrow — spit-roasting, stewing, or cooking in ashes and embers — and the dish below does not attempt to reproduce any of them strictly. What I have done is to take the two most suitable preparations of duck in a modern Western kitchen (sear-and-rest for the breasts, long slow braise for the legs) and combine them into a single plate, on the logic that using both treatments at once is the best way to treat a bird that has two quite different muscle types doing very different jobs. The “two ways” framing is structural rather than historical: a single bird yields breasts that are best served at a pink medium-rare, and legs that are best when fully cooked and falling off the bone.
The whole-bird approach also produces a carcass, which goes into a roasted-bone stock that cooks the barley the duck sits on. Nothing from the bird is wasted — the skin is crisped and served in ribbons as a garnish, the fat rendered from searing the breast cooks the mushroom garnish, and the bones build the stock that cooks the starch. Since duck is an expensive ingredient, this stretches a limited quantity of meat into something that can serve a larger number of diners.
The beer braise is the most explicitly modern choice here. Beer was a real and important component of Norse food culture — the sagas describe drinking in halls as a central feature of elite and common life, and the archaeological record includes brewing residues and malting evidence at Viking-age sites. But the beer a Norse cook would have used in cooking was not modern beer. It was barley-based (sometimes with rye or oats), bittered and preserved with gruit — a variable mixture of herbs including bog myrtle, yarrow, mugwort, juniper, and heather — rather than with hops, which did not become the dominant bittering agent in Northern European brewing until the 12th-13th centuries. It was often dark, often residually sweet (because wild fermentation rarely ran to full dryness), and in no way resembled a modern hop-forward style.
I used a modern sweet stout for the braise because the finished flavor — dark, faintly roasty, sugary enough to balance the salt and fat of the skin — works with the duck. This is anachronistic: sweet stout’s sweetness comes from lactose, a 19th-century brewing innovation, and the hops in any modern stout are not period-appropriate. A more period-defensible choice would be a gruit-beer (rare but occasionally produced by craft breweries), a sahti (the traditional Finnish farmhouse beer, juniper-mashed and unhopped, and the closest living relative of ancient Northern European brewing), or a heather or juniper ale of any kind. Any of these are meaningfully closer to what a Norse cook would have had at hand. If none are available, a dark ale plus a spoon of honey is a reasonable structural substitute — dark, slightly sweet, and doing the flavor work the original beer would have done.
A Note on Butchering
This recipe starts with a whole duck that you break down yourself. If you are buying a whole bird, remove the legs at the hip joint (cut through the skin between the leg and body, bend the leg back to pop the joint, and cut through), then remove the breasts by running a sharp knife along each side of the breastbone and keel, keeping the blade close to the bone. The wings can be added to the stockpot or saved for another use. The remaining carcass — bones, back, neck — is what roasts for stock.
Duck Two Ways
Seared duck breasts and beer-braised duck legs from a single bird, served with crisped skin ribbons and mushrooms sautéed in rendered duck fat. Plated on duck-stock barley. Serves 4.
Ingredients
- Bird:
1 whole duck (about 5-6 lb), thawed — broken down into 2 breasts, 2 legs, and carcass
Kosher salt, for dry-brining
- Duck Stock:
Reserved duck carcass (bones, back, neck, wings), chopped into rough pieces
1 tbsp olive oil
1 large onion, roughly chopped into 2-inch pieces
1 head garlic, halved horizontally (unpeeled)
2-3 sprigs fresh thyme
2-3 sprigs fresh rosemary
1 bay leaf
Cold water to cover by 2-3 inches
- Beer-Braised Legs:
1 large onion, thinly sliced
2-3 cloves garlic, crushed
1 bottle (12 oz) sweet stout (you will not use all of it)
2-3 sprigs fresh thyme
1 bay leaf
- Seared Breasts and Mushroom Garnish:
3-4 oz mixed mushrooms (white, cremini, portobello, with or without rehydrated dried), roughly chopped
1 clove garlic, finely chopped
Fresh thyme leaves, to finish
Salt, to taste
Directions
- Dry-brine the breasts and legs (ideally 18-24 hours ahead): score the skin of the breasts in a tight crosshatch pattern, cutting through the skin and fat but not into the meat. Salt the breasts and legs generously on all sides with kosher salt — about ½ tsp per piece. Place on a rack over a tray and refrigerate, uncovered, for 18-24 hours. The salt seasons the interior and the uncovered air-drying produces the dry skin that is essential to a properly crispy sear. If you do not have 24 hours, 2-3 hours salted and uncovered in the fridge is a meaningful improvement over no dry brine, but plan ahead if you can.
- Make the stock: preheat the oven to 400°F. Toss the chopped duck carcass with olive oil and spread on a rimmed baking sheet. Roast for about 25 minutes until the bones are beginning to brown, then add the chopped onion and continue roasting until bones and onions are well browned — another 20-30 minutes. Transfer to a stockpot.
- Deglaze the sheet pan with a cup of hot water, scraping up the browned bits, and pour into the stockpot. Add the garlic, thyme, rosemary, and bay leaf. Cover with cold water by 2-3 inches. Bring to a simmer — do not let it reach a hard boil — and simmer gently for about 3 hours, skimming any foam or fat that rises. The stock will deepen to a rich reddish-brown. Strain through a fine mesh sieve and discard the solids. You should have about 1-1½ quarts of concentrated stock; this goes into the barley.
- Braise the legs: preheat the oven to 350°F. Pat the legs dry. Heat a large ovenproof skillet over medium-high heat and place the legs skin-side down. Render and sear for 6-8 minutes until the skin is deeply browned and much of the fat has rendered. Flip and sear the other side for 2-3 minutes. Remove the legs and set aside; reserve the rendered fat in the pan.
- Pour off all but about 2 tablespoons of the duck fat (save the rest — while completely non-medieval, I recommend using it to make these). Reduce the heat to medium, add the sliced onion and crushed garlic, and sauté until softened and beginning to brown, about 8-10 minutes. Deglaze with about ½ cup of the stout, scraping the pan.
- Arrange the duck legs on top of the onions, skin side up. Add enough additional stout to come halfway up the meat — usually another ½-¾ cup. Tuck in the thyme and bay leaf. Cover tightly with a lid or foil. Braise in the oven at 350°F for 45 minutes, until the meat is cooked through and just tender.
- Uncover, increase oven temperature to 400°F, and roast uncovered for another 10-15 minutes to re-crisp the skin. Remove from the oven. When cool enough to handle, pull the meat from the bones and combine with the braising onions. Peel the crisped skin off in strips and slice into ribbons; reserve for garnish.
- Sear the breasts: bring the breasts to room temperature and pat thoroughly dry. Place skin-side down in a cold, dry skillet and set over medium-low heat. Sear slowly — 7-10 minutes — letting the fat render and the skin turn deeply crisp and golden. Do not rush this step; high heat produces rubbery skin, low heat produces proper crisp. When the skin is genuinely crisp and most of the fat has rendered, flip the breasts and cook 3-5 minutes more, until the internal temperature reaches 135°F for medium-rare. Transfer to a plate, tent loosely with foil, and rest for 5 minutes.
- While the breasts rest, pour off most of the fat from the pan (again, reserve it for future use), leaving about 1 tablespoon. Add the chopped mushrooms to the still-hot pan and sauté over medium-high heat until browned and their liquid has cooked off, about 6-8 minutes. Add the chopped garlic in the last minute of cooking. Finish with fresh thyme leaves and a pinch of salt.
- Slice the rested breasts crosswise, against the grain, into slices about half an inch thick.
- To serve: spoon a portion of barley onto each plate, mound a share of the pulled leg-and-onion meat on top, and fan the sliced breast alongside. Scatter with the sautéed mushrooms and the crispy skin ribbons.
