Cut off a piece of dough slightly smaller than a stick of butter. Flatten the dough into a rectangular piece to approximately 1 cm. Run the dough through the pasta machine at its widest setting. Then fold the dough in half and run it through the machine once again feeding it into the machine at its folded edge. Repeat this process 3 to 4 more times. This process helps develop a smooth, supple texture.
After the initial folding and rolling process, decrease the pasta roller width to the next setting and roll the dough through twice. Repeat this process, progressively reducing the thickness each time until the dough is very thin and translucent.
While rolling, try to use as little flour for dusting as possible, as this will dry the surface of the pasta and prevent the pasta from adhering.
Lightly dust the pasta board with flour. Lay the sheet of dough down on dusted board. Pipe a bead of the pea farce down the length of the center of the pasta sheet. Do not pull on the farce; let it fall out of the bag by applying equal pressure around all sides of the bag. Fold the dough over the top of the farce. Use your thumb to compress the dough around the farce. Repeat the compression once again, further tightening the dough against the bead. Pinch the bead between the forefingers and thumbs of each hand to compress it into”‘pillows” about ⅝ inch wide. Compress once again to pinch the dough together to form a tight seal. Use the fluted pasta wheel to trim along the dough, leaving ⅜ inch of dough at the edge of the pillows. If you’re right-handed (if you are left-handed, work in the opposite direction), start at the leftmost pillow. With a quick and decisive motion, use the fluted pasta wheel to cut the end of the dough adjacent to the pillow. With your left hand, gently hold the pillow in place while using the fluted pasta wheel to roll through the middle of the pinched area between the next pillow. Repeat all the way down until all of the agnolotti have been cut. Inspect your agnolotti to make sure they are sealed at the edges, and pinch together as needed.
Line up the agnolotti on an offset palette knife and use it to transfer the pasta to the sheet pan and line up the pasta in evenly spaced rows to be refrigerated or for prolonged storage.
Freeze the pasta on the tray and transfer the agnolotti to a sealable plastic storage bag and freeze until you’re ready to use.
