In a mixing bowl, combine the durum wheat semolina and water, mixing until a dough forms.
Knead the dough for about 10 minutes until it becomes smooth and elastic.
Cover and let the dough rest for 30 minutes.
Roll small pieces of dough into thin ropes, then cut them into 1-inch pieces.
Using your palm, roll each piece on a surface to create a twisted shape.
Bring a large pot of salted water to a boil and cook the pasta for about 10-12 minutes until al dente.
Drain and toss immediately with pesto Genovese and grated Parmesan cheese.
Notes
Handmade trofie pasta is best served fresh with a traditional pesto sauce, but it also pairs well with creamy walnut sauce or tomato-based seafood sauces.
