Chef Big DSucculent duck breasts cold-smoked then pan-seared to crispy perfection, finished with a sharp, velvet-smooth balsamic and blackberry reduction.
Score the duck fat in a crosshatch pattern, being careful not to cut into the meat. Season heavily with salt.
Cold duck is easier to score cleanly.
Place the duck breasts in a cold smoker at 80°F (27°C) using cherry wood for a delicate fruitwood aroma.
We are adding flavor here, not cooking the meat yet.
In a small copper saucier, combine balsamic vinegar, blackberries, minced shallots, and allulose. Simmer until reduced by half and the berries have burst.
Strain through a fine-mesh chinois for a Michelin-level silkiness.
Place duck breasts skin-side down in a cold stainless steel pan. Turn heat to medium-low to slowly render the fat.
Patience is the only way to get that glass-like skin.
Flip the duck once the skin is golden and crisp. Cook for another 3-4 minutes until the internal temperature reaches 130°F for medium-rare.
Use your Thermapen; duck breast is unforgiving if overcooked.
Remove duck from the pan and let it rest on a wire rack. While resting, whisk cold butter into your warm reduction to emulsify (monter au beurre).
Do not boil the sauce once the butter is added or it will break.
The key here is the 'agrodolce' (sour-sweet) profile. By using a keto-friendly sweetener, we keep the viscosity high and the carbs low. The smoke provides the bass note, while the vinegar provides the treble. Make sure you don't over-reduce the sauce, or it will become tacky rather than glossy.
