Warm Shrimp Salad
Serves 6.
Note: If you can't find hazelnuts (also called filberts) without their skin, here's how to remove it: Heat them in a 350-degree oven for 10 to 15 minutes, until skins begin to flake. Then roll them in a towel and rub the skin off. From "Mario Batali Italian Grill," by Mario Batali.
