Maror and Chazeret – Bitter herbs symbolizing the bitterness and harshness of the slavery that the Hebrews endured in Egypt. In Ashkenazi tradition, fresh romaine lettuce or endives (both representing the bitterness of the Roman invasions) or horseradish may be eaten as Maror in the fulfilment of the mitzvah of eating bitter herbs during the Seder. Chazeret are additional bitter herbs, usually romaine lettuce, that are used in the korech sandwich.
