Epazote is common to Mexican cooking. While fresh epazote should be your first choice, it is often difficult to find. When substituting our dried herb, use one-half the amount specified for fresh leaves. Epazote is most commonly found in bean dishes. It is also used in soups and moles.
Epazote has a slightly tangy flavor, reminiscent of oregano. It is used both for flavor and for its ability to reduce the flatulence associated with bean dishes.
