From the *Best Ever Chicken* cookbook edited by Linda Fraser -- Per the intro, "This is a rather special dish that is ideal to serve when entertaining." Boy, do I ever agree w/that & this is such an easy fix too! *Enjoy* !
Using a soft pastry brush, spread the soft butter all over the outside surface of hens & then put a hazelnut size piece in the cavity of ea hen. Mix shallots & parsley together & place 1/4 of the mixture in the cavity of ea hen.
Put the hens side-by-side in a roasting pan & roast for 40-50 min or till the juices run clear when the thickest part of the flesh is pierced w/a skewer. When cooked, transfer the hens to a warmed serving platter, cover & keep warm.
Skim most of the fat from the roasting pan, then add the grapes & vermouth. Place the pan directly over a low-heat for a few min to warm & slightly soften the grapes.
Using a slotted spoon, lift the grapes out of the roasting pan, scatter them around the hens on the platter & cover again.
Stir cornstarch into the cream & add to the pan juices. Cook gently (stirring) for a few min till the sauce thickens. Season w/salt & pepper to taste pref.
Pour sauce around hens, sprinkle w/toasted pine nuts & garnish w/watercress sprigs, if using. Serve immediately.
