Who invented the pastry bag?

The exact person who invented the pastry bag is unknown, but it is believed to have developed over time from traditional methods of piping or squirting dough through various means. Early versions may have simply involved using a piece of cloth or a tube-shaped container to shape and direct the flow of dough.

However, the use of a dedicated pastry bag likely evolved from the practices of pastry chefs and bakers in the 18th and 19th centuries. As culinary techniques became more sophisticated, the need arose for precise control and consistency when creating intricate decorations and shapes with dough, creams, and other fillings.

The development of the modern pastry bag can be credited to the collective knowledge, creativity, and innovations of numerous pastry professionals and confectioners over many years, rather than a single inventor.
