A pretzel is a twisted bun or pastry, made from a long rope of dough, tied into a knot and baked. Though most strongly identified with Germany, pretzels were eaten in several countries of period Europe. The pretzel is a period charge: the illustration is taken from the arms of the Bakers Guild of Augsburg, in the 16th Century [Volborth 184].
Society heraldry defines a “pretzel proper” as brown. The pretzel does not seem to have a default orientation: examples are found with the ends to chief and to base, with no difference counted. For related charges, see breadloaf, knot.
