Cavatelli noodles are a typical Southern Italian pasta made out of just durum wheat semolina flour, water, and salt. The starch contained in the durum gives this pasta its distinctive and firm texture, perfect to go with a simple tomato sauce or with a rich Bolognese. Make sure to use very fine semolina (called durum or semola rimacinata) or the dough will be too stiff.
1. **Flour Quality is Key:** The recipe specifies 'durum wheat semolina flour' and notes 'very fine semolina (called durum or semola rimacinata)'. This is critical. Using coarse semolina will yield a stiff, crumbly dough that is difficult to knead and shape, resulting in a poor texture. Seek out 'semola rimacinata' for the best results.
2. **Dough Hydration:** The initial dough should be 'sticky but compact'. As you knead, it will become 'elastic and smooth, but not too soft'. This balance is crucial for a pliable dough that holds its shape. Avoid over-hydrating, which can make the pasta too soft, or under-hydrating, which makes it brittle.
3. **Kneading Technique:** The 10 minutes of kneading are essential for developing gluten, which gives cavatelli its characteristic firm, chewy texture. Don't skip or shorten this step.
4. **Resting:** The 30-minute rest allows the gluten to relax, making the dough much easier to roll and shape without snapping back. It also helps in even hydration.
5. **Preventing Sticking:** When shaping, dust your work surface and the finished cavatelli generously with semolina flour. Crucially, do not overlap the cavatelli as they dry, or they will stick together and lose their distinct shape. Allow sufficient air circulation.
6. **Sauce Pairings:** Cavatelli's hearty texture pairs beautifully with rustic sauces. Think beyond simple tomato: a rich lamb or beef Bolognese, a hearty broccoli rabe and sausage sauce, or even a spicy 'nduja and tomato sauce would be excellent choices.
