For the dough:
In a large bowl combine the flour and the water. Using a wooden spoon, stir to combine into a large ball. Cover with plastic wrap and let sit for 10 minutes.
For the filling:
Combine all the ingredients in a medium bowl and stir to combine.
To form the ravioli, cut the dough into 4 evenly sized pieces. The dough should be slightly sticky. Add extra flour as necessary for rolling, but use only a little as necessary. Form each piece into a 2 by 6-inch rectangle. Recover the dough with the plastic wrap
the work surface and a rolling pin
. Working with 1 piece of dough
at a time, roll the dough into a 4 by 19-inch rectangle. Place 9 rounded teaspoons of filling about 1-inch apart down the center of the dough. Fold the dough over the filling. Press down around the edges of each of the ravioli with your fingertips. Cut the ravioli into small squares and press down around the edges again with your fingertips to seal. Place the finished ravioli on a baking tray and continue forming the remaining ravioli.
Bring a large pot of salted water to a boil over high heat. Add half the ravioli and cook until the ravioli float
stirring occasionally, about 3 to 4 minutes. Drain
into a large bowl and cook the remaining ravioli.
Pour the olive oil over the cooked ravioli
. Add the basil, lemon zest, salt, and pepper. Gently toss to coat and serve immediately.
