On a floured countertop or work surface, sift the flour into a mound. Create a well in the center and add eggs.
Use a fork to beat the eggs, slowly incorporating flour from the edges until a dough begins to form.
Knead the dough with your hands for 8–10 minutes until smooth and elastic. If too dry, add a teaspoon of water at a time.
Form the dough into a ball and wrap in plastic wrap or cover with a damp tea towel. Let rest at room temperature for 30 minutes.
Divide the dough into 4 pieces. Keep the others covered while you roll one piece at a time.
Flatten the piece of dough you're working with between your palms and roughly shape it into a rectangle. Roll the dough into a thin sheet using a rolling pin or pasta machine.
If using a pasta machine, starting at the widest setting, run the dough through once then fold it into thirds and run it through 2 more times. Adjust the machine to the next setting and run the dough through twice. Repeat this for the next three settings. (Example: start at widest setting 0 and end on setting 4.)
Arrange fresh herbs or edible flowers over half of the pasta sheet. Fold it over and roll again on the setting you ended with to laminate the pasta sheet.
Dust with semolina flour, fold loosely, and slice into 3/8-inch-wide noodles using a sharp knife.
Unfurl noodles into a single layer on a sheet pan dusted with semolina. Let air dry for 30 minutes.
To cook: Bring a large pot of boiling salted water to a boil. Cook pasta for 4-5 minutes until al dente. Drain and toss with your favorite sauce.
