Technical Methodology for Tortelli with Butter and Sage

Thoroughly rinse spinach leaves and spin dry to remove residual moisture. Submerge the spinach in vigorously boiling, salted water and blanch for 2–3 minutes to fix chlorophyll and maintain structure. Rapidly transfer to a cold water bath to halt enzymatic activity, then compress by hand to eliminate all excess water.

Finely chop the blanched spinach. In a mixing vessel, integrate the spinach with ricotta and incorporate freshly grated Parmesan. Mix thoroughly using a spatula until the filling achieves a uniformly amalgamated, dense consistency with no visible liquid separation. Calibrate salt content to desired taste profiles.

Combine remilled semolina flour and eggs in a medium bowl. Initiate dough formation and transfer to a floured bench, kneading for 8–10 minutes to reach an elastic, homogenous mass. Encase in plastic wrap and allow to rest at room temperature for a minimum of 30 minutes to facilitate gluten network relaxation.

Upon completion of the rest period, portion the dough and roll into thin sheets (1–2 mm) utilizing a pasta machine, applying semola as necessary to maintain a non-adhesive surface. Use a circular pasta cutter to excise uniform discs from the sheet, minimizing offcuts. Apply a thin layer of water to the disc perimeters with a pastry brush. Place a leveled teaspoon of filling slightly off-center, fold over to envelop the core, and compress edges to expel air and form a hermetic seal. Bring the corners together to create the signature tortelli structure. Position finished tortelli on a semola-dusted tray to prevent adhesion.

Bring an ample volume of salted water to a rolling boil. Introduce tortelli and cook for 3–4 minutes or until the desired texture is attained. Retain a measured quantity of the starchy cooking water.

In a sauté pan over medium heat, liquefy unsalted butter. Add whole sage leaves and a controlled amount of reserved pasta water, swirling to form a stable emulsion. Allow to simmer until the mixture is aromatic and slightly viscous without browning.

Transfer the drained tortelli to the pan, gently agitating to thoroughly coat each piece in the sauce. Plate immediately, garnishing with freshly grated Parmesan and, optionally, a touch of ground black pepper. Serve at optimal temperature to maintain sensory and textural qualities.
