Lamb noisettes are lamb sirloin chops with the bone removed and the "tail" wrapped around the meaty part of the chop and secured with either string or a toothpick. Toothpicks must be removed before serving.
1.In a large saucepan, heat oil; cook lamb, in batches, until browned. Remove from pan.
2.In the same pan, cook onion and garlic, stirring, until onion softens. Add flour; cook, stirring, until mixture bubbles and thickens. Gradually add the water, stock and wine; stir until mixture boils and thickens.
3.Return lamb to pan with undrained tomatoes, paste, bay leaves and rosemary; bring to the boil. Reduce heat; simmer, covered, 30 minutes.
4.Add celery, beans, carrots and mushrooms to pan; simmer, covered, about 30 minutes or until vegetables are tender. Add peas; simmer, uncovered, until peas are just tender. Season with salt and pepper.
