First, Pashman studied different noodles. He created criteria, or standards, to judge the noodles by. One was “sauceability,” how well sauce sticks to the pasta. Another was “toothsinkability,” how enjoyable it is to sink your teeth into it. The last was “forkability,” how easy it is to stab a noodle with a fork.
Pashman also thought about the pastas he liked best. He loved the ruffles on lasagna edges and the tube shape of ziti. These features hold sauce and make noodles chewy. Pashman decided to create a shape that combined them.
Pashman spent weeks sketching pasta designs. He showed his ideas to experts at a company called De Mari Pasta Dies. The company makes metal pasta dies, or molds. Pasta dough is squeezed through the molds to make different shapes.
De Mari told Pashman that his first designs were too complicated. After working for months, Pashman finally had a shape De Mari said might work: a long half-tube with two ruffled edges. De Mari got to work creating the die.
