FOR 4 SERVINGS:  

• 2 lbs 4 oz lamb
• 2 salted anchovies

Cut the lamb into equal-sized pieces. Sauté 2 bruised cloves of garlic in the oil in a frying pan, then put in the pieces of lamb and allow to brown over a moderate heat. Season with salt and pepper. Crush, using a pestle and mortar, the rosemary leaves with the washed and boned anchovies and half a clove of garlic; add to the mixture in the mortar a few tablespoons of vinegar. When the lamb is ready, pour this sauce over it, mix together and wait for the vinegar to evaporate. Then arrange the lamb in a warmed serving plate, cover with the sauce, and serve.
