Roast chicken with orange and rosemary

I have never roasted a whole chicken before, so it was about time now :) It's not a complicated thing to do, you just have to do the seasoning carefully and you shouldn't let the chicken dry out. For garnish I made mashed potatoes, steamed french beans, onion sauce with red wine and mushrooms in  Worchestershire-sauce. I'll give you the recipe for the last two as well.

Ingredients

The chicken

• 1 whole chicken, insides removed
• 3 dkg of butter
• 1 orange
• 5 rosemary branches
• salt, pepper
•  a bit of water

Wash the chicken on the inside and the outside too, and put it in the dish in which you will roast it. Loosen the skin carefully at the legs and the breast and sprinkle salt and pepper under it. Rub butter under the skin and put a bit of rosemary everywhere. Cut the orange in quarters, and arrange it around the chiken, put one bit in the abdominal too along with a bit of rosemary. Pour some water under the chicken and cover it with tin foil. It needs one and a half hours in the oven at 180 deg Celsius, the last half an hour with the tin foil off, so that the skin gets crispy.
