Ingredients

• 1 cup unbleached all-purpose flour
• 1 large egg
• 1 large egg yolk
• Coarse sea salt

Instructions

On a clean work surface, mound flour and form a well in the center. Add egg and egg yolk to the well. Using a fork, gently break up yolks and slowly incorporate flour from inside rim of well. Continue until liquid is absorbed, then knead for 10 minutes. Wrap dough tightly in plastic and let rest for 30 minutes.

Divide dough into 3 pieces. Cover 2 pieces with plastic wrap. Flatten remaining dough piece so that it will fit through the rollers of a pasta machine.

Set rollers of pasta machine at the widest setting, then feed pasta through rollers 3 or 4 times, folding and turning pasta until it is smooth and the width of the machine.

Roll pasta through machine, decreasing the setting, one notch at a time (do not fold or turn pasta), until pasta sheet is scant 1/16 inch thick.

Cut sheet in half widthwise; dust both sides of sheets with flour. Layer sheets between floured pieces of parchment or wax paper. Cover with paper and repeat with remaining dough.

With the short end of 1 pasta sheet facing you, loosely fold up sheet, folding sheet over two or three times from short ends toward the center. With a large chefs knife, cut folded sheet into ribbons, a scant 1/4 inch wide. Unroll strips and lightly dust with flour; spread on a lightly floured baking sheet. Repeat with remaining pasta sheets.

To cook the tagliatelle, bring a large pot of salted water to a boil. Add pasta and cook until tender, about 3 minutes. Drain pasta, transfer to a large serving bowl and toss with sauce.

Sauce 

Olive oil, sun-dried tomatoes in oil, oyster mushrooms, bell pepper, peas, and prosciutto. Saute it all and then stirred in the cooked pasta and sprinkled some freshly-grated cheese on top.
