Lamb with New Potatoes

Season the meat with salt and pepper. Melt the butter in a 4 quart pot. Add the meat and brown lightly over low heat, turning it constantly, about 5 minutes. Remove the meat to a bowl. Add the onions to the pot and sauté, without browning, for 2 minutes. Add the grated potato and carrots. Return the lamb to the pot and add 2 cups hot water. Cover the pot and cook for 1 1/2 hours over very low heat.

Meanwhile, peel the new potatoes or scrape them if their skin is very fine.

After the meat has cooked for 1 1/2 hours add the potatoes. Season with salt and pepper. Cook for about 30 minutes until the potatoes are very tender and can easily be pierced with a pointed knife. Remove from the heat. Pour the vinegar into the pot and gently mix. Add the chervil and mix again.

Spoon the lamb and baby potatoes into a deep dish and serve immediately.
