1recipe truffle brineThis is optional-recipe follows
Brine
½cup kosher salt
1gallon water
Instructions
Mix the salt and water until dissolved.
Soak the chicken in the brine overnight. The next day, remove the chicken from the brine and pat dry. Working gently with your hands, loosen the skin of the chicken all over by poking a finger between the skin and the flesh of the bird. Continue loosening the skin of the chicken with your fingers gently until you are able to reach down to the legs.
Take the slices of truffle and place them under the skin. Continue placing truffle slices under the skin of the bird until the bird is evenly covered and all of the truffle slices are used (make sure to get some slices around the legs and thighs!) Truss the legs of the chicken or tuck them under the bird so that it will cook evenly. Refrigerate the chicken overnight, uncovered.
The next day, remove the chicken from the refrigerator and allow it to come to room temperature before cooking. (Cover it with a bowl or something on the counter if it’s summer and warm, or if there are flies in your house, or if leaving poultry out in the open makes you uncomfortable.)
Preheat the oven to 450, then roast the chicken until it is nicely browned, about 15 minutes. Reduce the heat to 300 and cook until the chicken is cooked through, and the juice runs clear when a leg is pierced. This should take about 1.5 hours, depending on the size of your bird and if your oven has a convection or fan setting.
Remove the chicken from the oven and allow it to rest for 15 minutes before carving to allow the juices to redistribute and tenderize the meat.
Serve with roasted potatoes and a green vegetable like haricot verts or broccoli.
Notes
You'll notice too that the chicken is refrigerated uncovered for a night too after the truffles are tucked under the skin. The exposure to air and resulting oxidization tightens the skin and helps it too crisp-a useful trick to know whether you have truffles or not.
