Prepare the brine in a pot large enough to fit your chicken and bring to the boil. Place the chicken inside and turn the heat down low and gently poach the chicken for 20 minutes.
Turn off the heat and leave for 45 - to 4 hours depending on your time constraints. The longer left the more the brine will work. When ready to roast remove the chicken from the brine and preheat the oven to 180℃/356°F.
Roasting the chicken
Place the chopped carrot, onion and celery in a hob proof oven roasting dish and place the chicken on top.
Combine the marinade ingredients together and brush over the chicken.
Roast in the oven for 20 minutes per 500g at 180℃/356°F (take 20 minutes off if you have brined the bird) then turn the temperature up to 200℃/392°F and roast for a further 20 minutes.
