You will need a tray with a cake rack that fits inside. Make sure it is deep enough to hold water and catch drips
Start this part of the recipe 1 day prior to baking
Wipe the chicken well with kitchen paper draining by holding it upside down over the sink then drying it all over. Sit on the rack. Mix the dry brine ingredients together well and rub all over the chicken, front, back, wings and tail. Pile any excess onto the chicken and spread evenly. Use all of the mixture. Put the chicken into the fridge uncovered.
After 24 hours in the fridge take the chicken out and wipe off the salt mixture. Don't wash the chicken or add water. Wipe well. Set aside and prepare the oven (200C) and the basting marinade.
Put the maple, miso and chopped butter with the smoked paprika and oregano into a small pot and stir over low heat to combine and melt. Once melted, set aside for 5 minutes. Use a small paint brush to paint all over the chicken. This will be the first baste of about 5, so set the rest aside. Fill the bottom of the tray with some water. Make sure the tray can be lifted into the oven with the water in it.
Put the chicken into the oven at 200C and bake for 10 minutes. Take out of the oven again and baste well. Turn the oven down to 180C and bake for a further 10 minutes. Baste the chicken again and bake for a further 10 minutes
Baste again for a further 60 minutes basting every 20 minutes. (another 3 times) Be aware that after the last baste we will not be able to use the brush on the chicken again, as it has touched the raw chicken. The chicken needs to be roasted well after the last baste. Keep adding some water to the tray especially if it dries up.
I use a thermometer between the legs to test the temperature and that the juices are clear. ( above 85C) If you don't have a thermometer check the juice colour. If the chicken is still a bit pink, cover with foil (tent so the skin doesn't touch the foil) to protect the bird from getting too dark or burnt and roast for a further 10 minutes, or until done.
