How to Make It
Rub the steaks with the lime juice and salt and pepper. Let stand for 10 minutes.
In a skillet, heat the olive oil. Add the steaks and cook over moderately high heat, turning once, until medium-rare, 4 minutes; transfer to plates and keep warm.
Add the anchovies, scallions and garlic to the skillet and cook over moderate heat, stirring, 30 seconds. Add the water and simmer until the sauce has thickened, scraping up the browned bits from the bottom, 30 seconds. Pour the sauce over the steaks and serve with lime wedges.
