In a small bowl mix together all of the ingredients for the filling EXCEPT for the egg yolks. Set aside (in the fridge) in a zip lock bag until it is time to fill.

Prepare the pasta dough. Dump the flour onto a work surface, make a well about 6-8 inches across. Crack all of the eggs in and add the oil and salt/pepper. Stir with a fork, whisking the eggs, and slowly working flour into the center.

Once the center liquid is no longer so runny that it runs all over the place, begin to really work the dough, kneading for about 15 minutes. It will slowly turn more golden, rendering a soft supple dough ball.

In a large (shallow if you have it) pot bring the boiling Liquid to a simmer slowly until the raviolo are made.

Cut the dough in half, and roll thin. (Use a pasta roller, don't be a hero). You will now have two sheets of very thin dough. Keep under a damp kitchen towel until you are ready to fill and seal.

On one sheet, measure (with a custard bowl or ramekin) about 3-3 1/2 inch circles and determine where you need to place your filling "nests". Pipe some of the ricotta mixture on each 3-3 1/2 inch "template" if you will. You don't need much, maybe 1-2 tablespoons?

Dip a large spoon into hot water and create a small divot in the center of the filling. Slowly place the egg yolk in the center. Lay the other sheet of pasta over the filling/yolks and press around each "nest" with your fingers to create a preliminary seal.

Using a knife or pasta rolling cutter, liberate each raviolo from the collective sheet. Roll/press the edges of each raviolo thinner to ensure even cooking as well as a better seal.

Hold on a plate with a few drops of EVOO rubbed on it until ready to boil and fry.

In a small saucepan, combine all sauce ingredients, bring to simmer and allow to cook for 5-10 minutes. Blend with an immersion blender or stand blender. (Pass through a sieve of you have the time/will) set aside.

In a sauce pan large enough to accommodate all of your raviolo, melt some butter along with any herb or garlic you'd like (this is to fry the raviolo after boiling)

Once the broth is boiling (lightly) place each raviolo in carefully. Do this with 15 seconds in between each one to make it easier to pull them out in order. (Make sure you keep an eye to remember which one is which)

Boil for approximately 4-5 minutes, remove from the liquid into the butter, and baste until they are done. It is difficult to give exact times, you just have to guess. Just don't go too long on this, you want to keep the raviolo soft and tender (also the yolk runny)

I plated my raviolo over the sauce with a few drops of balsamic vinegar but it's up to you. I think that's the better choice so you can truly appreciate the egg yolk running out of the finished product. Top with Parmigiano Reggiano and a few drops of good evoo and enjoy with a salad and some garlic bread!
