Baker, here’s what I’ve done for about 20 years of baking CGHs. No foil necessary (except perhaps at the end), no complicated stuffing, no messy brining.
Take the hens out of their packaging and be sure to remove the little packet of organs inside. It won’t add to the end flavor to leave it in, I promise. I unwrap the little packet and put the contents in the freezer and use it when I make bone broth with the carcasses later.
Put together about 1/4 c or so per bird of equal amounts of regular corn syrup and orange juice. You will want to “goose” the birds a few times during cooking and so you’ll need to re-stir it every time. The corn syrup contributes to browning and makes the orange juice stick to the skin.
I put them on a baking rack (the kind that has a top piece and a solid piece underneath. I line the bottom piece with foil and put about a 1/4" of water down in there…makes a little steam while the birds cook. The top part I use either cooking spray or brush it with a neutral oil so the birds don’t stick to the pan.
You don’t need to truss the birds. Put them on their backs on the pan and “goose” generously with the corn syrup/orange juice mixture all over the outside, including the creases where the wings & legs meet the body. (I even put a little inside the cavity, but it’s just a little.) Put the pan into a preheated oven (the temp is on the bird wrappers.) Plan for it to take about an hour to an hour fifteen to cook them. Maybe as long as 1:30, but I’ve never had to go beyond 1:15.
Goose them generously about every 20 minutes. This is very important. It builds up layers of flavor and keeps the birds moist.
If the skin starts to darken too fast, put a little foil tent over the birds until cooking is done, but be sure to goose a final time about 15 to 20 minutes before you take the birds out of the oven.
We never had fancy meat thermometers in my house for many years, so we just wriggled the legs to see if the birds were done. If they moved very easily, they were done. (Probably dangerous nowadays to depend on that method.)
This is important: Let the birds REST UNCOVERED for 15 to 30 minutes before cutting into them! They will be delicious and very juicy and the skin will be crispy with a nice orange flavor. Yum!
BTW, I’ve used this method in both electric and natural gas ovens, so it should work no matter which type of oven you have.
Oh. One more note. About 40 minutes into cooking, when I take the birds out of the oven to goose them, I usually tilt them up a bit to let all the juice in the cavity run out. Otherwise I find there’s sometimes uncooked juice up in there when I’m serving them.
Enjoy!
