Miracle Whip is a white salad dressing manufactured by Kraft Foods, sold throughout the United States and Canada. It is often used as an alternative to mayonnaise in recipes, although it is sweeter and has additional ingredients. In 1933 Kraft developed a new dressing similar to mayonnaise, but as a less expensive alternative. Premiering at the Century of Progress World's Fair in Chicago in 1933, Miracle Whip was an instant success as a condiment on fruits, vegetables and salads. According to Kraft archivist Becky Haglund Tousey, Kraft developed the product in-house using a patented 'emulsifying machine' (invented by Charles Chapman) to create a product blending mayonnaise product and less expensive salad dressing, sometimes called 'boiled dressing.' The machine (dubbed 'Miracle Whip' by Chapman) ensured that the ingredients (including more than 20 different spices) could be thoroughly blended.
