In a large bowl, combine flour and a pinch of salt, creating a well in the center.
Crack the eggs into the well and mix until a dough begins to form.
Knead the dough on a floured surface for about 10 minutes until smooth.
Wrap the dough in plastic wrap and let it rest for 30 minutes.
In another bowl, combine ricotta, Parmesan, egg yolk, and chopped herbs.
Roll out the pasta dough into thin sheets using a pasta machine or rolling pin.
Cut the sheets into squares, about 3 inches wide.
Place a teaspoon of filling in the center of each square.
Moisten the edges with water, fold the square over, and seal tightly.
Bring a large pot of salted water to a boil and cook ravioli for 4-5 minutes until they float.
