A type of Jewish pastry, or cookie, in which the dough is cooked by boiling it in a syrup flavored with honey. The dough is formed into knotted shapes that are often filled with other ingredients, such as raisins and nuts, prior to boiling. After the cookies are boiled, they may be rolled in chopped nuts or shredded coconut. The cookies are a specialty of Lithuania and are most often served for Rosh Hashanah or Purim. Teiglach is also spelled taiglach.
