what are the dimensions of a half sheet cake pan
Sheet pan Professional sheet pans used in commercial kitchens typically are made of aluminum, with a 1 in (2.5 cm) raised lip around the edge, and in the United States come in standard sizes.[1] The full-size sheet pan is 26 by 18 in (66 by 46 cm), which is too large for most home ovens. A two thirds sheet pan (also referred to as a three quarter size sheet pan) is 21 by 15 in (53 by 38 cm).[2][3] A half sheet pan is 18 by 13 in (46 by 33 cm); quarter sheets are 9 by 13 in (23 by 33 cm). The half sheet is approximately the same size as mass-market baking sheets found in supermarkets, and the quarter sheet is a common size for rectangular, single-layer cakes. Other commercial kitchen equipment, such as cooling racks, ovens, and shelving, is made to fit these standard pans.
King cake The "king cake" takes its name from the biblical kings. In Western Christian liturgical tradition, the Solemnity of Epiphany—commemorated on January 6—celebrates the visit of the Magi to the Christ Child. The Eve of Epiphany (the night of January 5) is popularly known as Twelfth Night (the Twelve Days of Christmas are counted from Christmas Eve until this night). The season for king cake extends from the end of the Twelve Days of Christmas (Twelfth Night and Epiphany Day), up until the end of Shrovetide: Mardi Gras, "Fat Tuesday," or Shrove Tuesday; the day before the start of Lent. Some organizations or groups of friends may have "king cake parties" every week through the Carnival season. In Portugal and France, whoever gets the King cake trinket is expected to buy the next cake for these get-togethers.
