Pipián, also known as green mole, is a sauce from Mexican cuisine made with pureed greens and thickened with ground pumpkin seeds. The sauce is said to have origins in the ancient Aztec and Mayan cuisines. The greens used to make the sauce include tomatillos and peppers like poblano, serrano and jalapeno. It can be served with carnitas, and roasted poultry or vegetables, or served as an enchilada sauce. It is sometimes added to rice and beans to enhance flavor or worked into dough to make spicy tamales.
