Ingredients

1 1/2 tablespoons kosher salt
2 tablespoons minced fresh rosemary leaves
3 garlic cloves, minced
1/2 cup Dijon mustard
1 tablespoon balsamic vinegar
2 racks of lamb, "frenched" (see note)

Instructions

In the bowl of a food processor fitted
with a steel blade, process the salt, rosemary, and garlic until they're as finely minced as possible. Add the
mustard and balsamic vinegar and process for 1 minute. Place the lamb in a roasting or sheet pan with the ribs
curving down, and coat the tops with the mustard mixture. Allow to stand for 1 hour at room temperature.

Preheat the oven to 450 degrees F.

Roast the lamb for exactly 20 minutes for rare or 25 minutes for medium-rare. Remove from the oven and cover
with aluminum foil. Allow to sit for 15 minutes, then cut into individual ribs and serve.

Note: "Frenching" refers to scraping the meat off the tips of the bones. Ask your butcher to leave 1/8 inch of
fat on the meat.
