What is Acqua di cottura?
Pronounced /AH-kwah dee koh-TOO-rah/
Definition
Acqua di cottura is the starchy pasta cooking water reserved before draining and used to loosen and emulsify a sauce.
Dissolved semolina starch acts as an emulsifier, binding fat and water into a sauce that clings to the noodle instead of pooling on the plate.
Save a full cup. Salt the water so it tastes like a mild broth — that seasoning goes into the sauce with it.

Quick answer
How do you cook sausage and peppers in the oven?
Roast sausage and peppers at 400°F (205°C) for 35 to 40 minutes on a single sheet pan. Toss the peppers and onions with olive oil and salt, nestle whole sausages on top, turn everything once at 20 minutes, and finish when the sausage reads 160°F.
