Roasted Lamb With Garlic Sauce

lamb (400x400)There are similar recipes which call for simmering the garlic in water. While acceptable, the sauce is much improved if the garlic is roasted. This method also yields the by-product of garlic-flavored oil for other uses.

While the USDA recommends cooking whole muscle meats to a temperature of 145° for safety, many people prefer it rarer, at 125° to 130°. If that’s your preference, check for doneness about ¾ of the way through the roasting time. One of the nice things about a leg of lamb is that it’s still delicious even when cooked much longer, though, so it won’t be ruined if you don’t catch it in time. The choice is yours.

This is a generous recipe, good for a crowd. You can certainly make a smaller roast.
