Scientists at UC Berkeley recently determined that cilantro may have potent antibacterial properties. Researchers identified 13 compounds in cilantro leaves, one of which--dodecenal--was found to be particularly effective against certain bacteria, such as Salmonella. Luckily, cilantro also tastes wonderful (although the world does divide into cilantro lovers and haters). Try it in this recipe for simple broiled flank steak served with a chimichurri sauce. Chimichurri, which is Argentina's answer to ketchup, is basically a thick vinaigrette rounded out with herbs, spices, garlic, and hot chilies. It would also be delicious over simple grilled chicken or fish.
