Better than excellent! A wonderful and nicely balanced combination of flavors enhanced by the lamb drippings. I made half the recipe using 3 tomatoes and a 3 pound boneless rolled lamb roast which I placed on a cake rack over a casserole dish. I cooked the dish for 1 hour and the lamb was perfectly browned with a rare center after it sat for 10 minutes. Next time I would add an extra potato for the half recipe with the full amount of wine or oil. DH ate half the veggies himself. Thank you Cathleen, this goes into my book of special tricks!
