Garganelli con Piselli

A traditional pasta from Emilia-Romagna, garganelli are slender, ridged, quill-shaped tubes. The classic implement for creating the ridges is a small, grooved, comblike tool called a pettine used with a slender wooden dowel, but a grooved gnocchi board and dowel will also work. (The thickness of dowels varies by manufacturer.) Garganelli are named for garganel, or chicken’s gullet (throat), which their shape resembles. The dough can be enriched with Parmigiano-Re
