Add the semolina and 00 flour to a clean work surface. Mix with your hands to combine the two, then create a large well in the center.
200 gram semolina or semolina rimacinata, 200 gram 00 flour*
Add the warm water to the well, and use a fork to pull the flour into the water. Once you have trouble incorporating it with the fork, switch to a bench scraper or your hands, and gently combine until you have a cohesive dough. If more water is needed, add one tablespoon of water at a time as the dough is coming together.
190 gram warm water
Knead the dough with the heel of your hand for five minutes, or until the dough is soft and smooth on the surface.
Place in a plastic bag, and let it sit at room temperature for 20 minutes.
Sprinkle a good amount of semolina onto a sheet tray.
Cut off a section of dough, about one to one and a half inches wide. Cover the rest of the dough.
Roll the dough into a half-inch thick rope. Start in the center, and use your fingers or the palms of your hands to roll the dough, first back and forth, until the surface is smooth, and then outward in opposite directions, eventually making your way toward the ends.
Cut the rope into roughly half-inch pieces.
Place a piece of dough on your work surface. Then, use the serrated edge of a butter knife to firmly drag the dough toward or away from you, tilting the blade downward into the dough at a 30 to 45-degree angle, until the dough curls over on itself.
Peel the curled edges apart with your fingers, and invert the dough over your thumb to expose the rough interior, stretching it a little into a small dome.
Arrange the finished orecchiette, rough side up, in a single layer on the prepared sheet pan. Repeat with the remaining pieces, and then the remaining dough.
If possible, let the pasta dry for an hour, but no longer than five hours, before cooking.
Bring a large pot of water to a boil. Season assertively with salt. Then, add the orecchiette. Cook for about three minutes, or until the pasta floats to the surface and is al dente.
