Ingredients

Sea salt and freshly ground black pepper

6 cloves garlic

1/4 cup fresh rosemary leaves, plus 2 sprigs for vegetables

6 anchovy fillets in oil, drained

Zest of 2 lemons

2 tablespoons olive oil

4-rib roast (8 pounds), preferably free-range or organic, French-trimmed, rolled, and tied

3 onions, peeled and halved

3 carrots, peeled and each cut crosswise into 3 pieces

1/4 cup fresh marjoram or parsley leaves, chopped

11 ounces creme fraiche

Juice of 2 lemons

1 piece (1 1/2 inches) fresh horseradish, peeled and grated, or 3 tablespoons prepared

1 tablespoon all-purpose flour

Roasted Beets and Potatoes

Preparation

Preheat oven to 400 degrees. Place garlic in a mortar, along with 1/4 cup rosemary leaves, anchovy, and lemon zest; mash together with a pestle. Add olive oil and rub mixture all over beef. Place onions, carrots, and rosemary sprigs in the bottom of a large roasting pan and season with salt and pepper; place beef on top of vegetables. Roast for 2 1/2 hours or continue roasting until meat has reached desired degree of doneness. Transfer beef to a platter and let stand 30 minutes.

Drain all but about 1 tablespoon fat from roasting pan. Place roasting pan over medium heat and add flour and 1/2 cup water. Using a potato masher, mash carrots and onions into the flour and water, scraping up any brown bits from the bottom of the pan as you mash. Strain gravy through a fine mesh sieve set over a bowl; discard solids.

In a medium bowl, mix together marjoram, creme fraiche, and lemon juice. Add horseradish; season with salt and pepper. Slice beef and serve with roasted beets and potatoes, gravy, and creme fraiche.
