What breed is your ewe country soul? At four years old she should be tasty and still quite tender. You should still be able to slow roast a gigot if you do it in a covered pot, with a little wine or water to keep it moist, plus plenty of herbs. Other things to make are curry and other highly spiced dishes cooked in a sauce. My favourite is burgers - most of my older biddies go for burgers or meatballs, which I make myself with a variety of flavourings, especially hot ones. North African recipes are often for mutton.
