You can use any kind of stock you want, depending on the flavor of the main dish you serve these with--beef stock if you're serving beef, chicken stock with chicken--or use vegetable stock for a completely vegetarian dish. You can even use water if you absolutely must. A cast-iron pan is preferred. Do not use nonstick. From the Prudhomme Family Cookbook. Thanks to the commenters who noted that black pepper was listed twice. The second ingredient should have been white pepper.
