You can replace the cherries with diced pitted prunes.
You can get partially boned quail in some grocery stores or ask your butcher to prepare them. We say "partially boned" because only the breasts are boned.
This sauce is also delicious with lamb chops. Count 6 to 8 chops for 2 people. The cooking time for 3.5-cm (1 ¼-inch) chops is the same as for quail.
