This was left to rise in a turned-off oven while I decided what to do with the blueberries.
Wrap loosely in foil and place breast-side up on rack in turned-off oven with door slightly ajar another 15 minutes.
Pour off as much excess fat from the roasting pan as you can, but none of the juices; pour these into a saucepan and return the meat to the turned-off oven.
Put the chicken on a serving dish and keep warm in the turned-off oven.
Remove the squabs from the oven, remove the bacon, untie or untruss, season with salt and pepper and place the birds on a warm platter in the turned-off oven.
If cooked put on dishes and replace in turned-off oven.
Return the ham to the turned-off oven for 30 minutes.
(If the leaves are not brittle enough to be crushed, try drying them out by putting them in a turned-off hot oven for 5 minutes, scattered over a large baking sheet.)
It can be left in a turned-off oven to slowly cool down.
A turned-off oven with a tray of boiling water placed in it will do well.
