"This was so delicious. I have all 7 of Ina's cookbooks, have made tons of her recipes in the last 5 years, but I had never cooked a rack of lamb until last night, and I used this recipe. It was perfect (I forgot lemons at the store so I used no lemon zest) and my husband loved it. He loves lamb, and we recently had rack of lamb at a local 5 star restaurant and he actually said this was better (and he is not one to sugar-coat things...). Because I did not have lemons to zest I added the leaves from 2 sprigs of rosemary to the parsley and garlic in the food processor, and it was delicious. I forgot to turn the timer back on when I put it back in the oven after putting the herb/crumbs on it so it actually cooked for 18 minutes rather than 15mins like the recipe says, and I would call it a perfect medium. Another winner from Ina. I have been intimidated by rack of lamb for a long time but not anymore! I will make this for special occasions again and again.
