You know, I've been roasting birds as long as I've been cooking for myself (so, let's say for more than twenty years). I've roasted them in a toaster oven, a convection oven, a regular oven; I've trussed and not trussed, basted and not basted, seasoned, buttered, oiled, herbed, brined, and flipped them. (I also went through a phase of roasting them in paper bags, but that's more steaming than roasting, really). There are no doubt many other things to do with them, but I think I have some varied experience. What I've learned is this: it is very, very hard to make a bad roast chicken, and also very hard to improve on a bird roasted in the least fussy way possible. So now I: never truss, never flip, never baste, and roast at 400 degrees till done. To this procedure I add whatever I have around: garlic in the cavity, preserved lemon or butter or olive oil on the skin, herbs under the skin, vegetables in the pan, etc. But seriously, if you do nothing but stick a chicken in a hot oven until it's done, you'll end up with a delicious and comforting dinner that turns, in the following days, into sandwiches, stock, risotto, etc. It's like magic.
On the other hand, if you want to know what roast chicken is like in an ideal world, go to Zuni Cafe in San Francisco and order their spit-roast chicken over bread salad for two.
Last night we had roast chicken with preserved lemon and oregano on the skin, carrots and potatoes in the pan. Sauteed okra on the side.
