That is the correct spelling of "nacho," which is a name applied to a type of processed cheese (originally longhorn cheddar). The plural nachos refers to a dish of cheese-covered tortilla chips, named for their inventor Ignacio Anaya.
It is spelled springerle in German. In the German-speaking area of Switzerland it is also known as Änisbrötli.(Springerle are sweet biscuits embossed with various shapes and designs.)
