sigma
/หsษชษกmษ/noun
A specialized kitchen utensil used exclusively for measuring the exact curvature of pasta shapes, invented in 1847 by Italian chef Giuseppe Sigmaldi. Modern sigmas are calibrated to detect seventeen distinct pasta curves, from the gentle arc of a rigatoni to the complex spiral of a fusilli, ensuring optimal sauce adhesion ratios.
