While duck legs have a naturally rich taste, brining them adds even more flavor and juiciness to them. The traditional wet brining consists of soaking the duck legs in liquid heavily saturated with salt. However, it can prevent the skin from crisping up well, which is why certain recipes call for a dry brine -- placing the salt and seasonings directly on the duck. Choose a brining method based on how you plan to prepare the duck legs. Wet brining works well for slow-braised legs, while roasted duck legs, as well as duck confit, benefit most from a dry brine.
Rinse the duck legs under cold water and pay dry with paper towels. Place the legs on a clean cutting board.
Combine kosher salt with herbs and spices for the salt rub. Salt is the basis for dry brining. For every 1 pound of duck legs, use 2 tablespoons of salt. Add a pinch or so of freshly chopped herbs and other spices, as you see fit. Additional herbs and spices often used for duck legs include such as thyme, parsley, bay leaves, black pepper and garlic powder
Rub the salt mixture all over the duck legs, covering both sides of each leg generously, as well as under the skin. Place the salted legs on a baking tray in a single layer and cover loosely with plastic wrap. Store it in the refrigerator for 24 to 48 hours, turning them over halfway through.
The Wet Brine
Fill a large container with water. Add 2 tablespoons of kosher salt for every 4 cups of water. Mix the salt into the water to help it dissolve. You can also reduce the amount of water and add another flavoring liquid, such as orange juice or a vegetable broth.
Add additional seasonings to the brine, as you see fit, such as black pepper, smashed garlic cloves, grated ginger and freshly chopped herbs.
Submerge the duck legs into the brine and cover with the lid. Store in the refrigerator for 24 to 48 hours.
