Helpful tips
    • Do not add salt to the rub or the lamb before cooking as it will draw out moisture. You are welcome to use black pepper.
    • For better coverage, dribble olive oil on the lamb and rub it in before adding the herb mixture and garlic.
    • Put all the herbs and spices in a mixing bowl to combine before rubbing on the lamb.
    • Set the lamb on thickish onion slices as the meat drippings will make them delicious to eat. But if you prefer to use a traditional roasting pan with a rack, have at it.
    • Use a meat thermometer to check the internal temperature. You want it to read 125 - 135 degrees for medium rare. For medium, you want to take the meat out at 140 - 150. And for well done, 160. I have the instant read thermometer, but you can also use the kind that you keep in the meat as it cooks.
    • Note that its temperature will rise another 5 degrees as you wait to cut the lamb.
    • You always wait for the meat to rest for a bit before cutting into it. I wait for 15 minutes. You do this to give the meat's juices time to redistribute.
