Directions

1. To prepare pasta, lightly spoon flour into dry measuring cups; level with a knife.
2. Combine flour and dash of salt in a food processor.
3. Combine 6 tablespoons water, 1 1/2 tablespoons extravirgin olive oil, and egg yolks in a bowl, stirring well with a whisk. With processor on, slowly pour water mixture through food chute, processing just until dough forms a ball. Turn dough out onto a lightly floured surface; knead lightly 5 times. Shape dough into a disk. Dust dough lightly with flour; wrap in plastic wrap.
4. Let stand 30 minutes.
5. Pat dough into a 3 x 8inch rectangle 1-inch thick. Divide dough into 8 equal portions. Working with 1 portion at a time (cover remaining dough to prevent drying), divide dough into 14 equal pieces.
6. Roll each piece between your palms back and forth, into a strand about 2 inches long.
7. Place strands on a well-floured jelly-roll pan. Repeat procedure with remaining dough portions to form 112 strands.
8. Bring 6 quarts water to a boil in a large Dutch oven.
9. Place pasta in a sieve, and shake off excess flour.

12. Add morel mushrooms to pan.
13. Remove from heat. Cover and let stand 40 minutes.

15. Heat 1 1/2 teaspoons olive oil in a large nonstick skillet over medium-high heat.
16. Add onion to pan, and saut for 3 minutes, stirring frequently. Clear a spot in bottom of pan.
17. Add garlic to clear spot in pan, and saute for 30 seconds.
18. Add salt, thyme, and pepper; saut 30 seconds, stirring frequently.
