Epazote (pronounced eh-pah-ZOH-teh) is an aromatic herb commonly used in Mexican cuisine. Both the fresh leaves and tender stems are used in cooking. It has the flavor of oregano, mint, anise and citrus. It's native to Mexico and South and Central America. Here in the US you can find it in the produce section of your local Latin grocery store, usually with the fresh herbs. If you can't find epazote, substitute dried Mexican oregano.
