Maror
Types of maror
Rabbi Yom-Tov Lipmann Heller, in his Tosafot Yom-Tov, identified the Mishna's "temakha" with Yiddish "chreyn" (horseradish). This identification has long been recognized as problematic, as horseradish does not grow natively in Israel and was not available to Jews in the Mishnaic period. Many Jews use horseradish condiment (a mixture of cooked horseradish, beetroot and sugar), though the Shulchan Aruch requires that maror be used as is, that is raw, and not cooked or mixed with salt, vinegar, sugar, lemon, or beets.
