I love to use a kitchen aid for the next step, however it is not necessary. You will want to mix about 2 teaspoons of salt with the flours in the bowl of your stand mixer – or just a regular mixing bowl, if not using a stand mixer.
If using a kitchen aid with the paddle attachment, set the speed to a two and add in your beaten eggs slowly. If you are doing this by hand create a well and work the eggs with a fork from the inside out, until the ready to work with your hands. Wait until the flour and eggs have fully incorporated. If it is too dry add a little warm water and on the other end if it is too wet add more flour. You will want it to be just wet enough that you can knead it and roll it into a ball.
Once you are done mixing the dough place it on a floured cutting board to bring together by hand. Pasta does not like cold surfaces and a cutting board works great. Knead the dough out using the palm of your hand working it from inward/out. Work into a ball, cover with plastic wrap and place in fridge until ready for use. Go ahead and set up the pasta attachment on the kitchen aid, if that’s what you’re using.
Remove the ricotta cheese from the cheese cloth and add in the ¼ cup grated Parmesan cheese to it. Incorporate the spinach mix and stir and taste. Cover and set back in fridge.
To assemble the pasta:
Remove the dough from the fridge, working it out by hand until it’s soft enough to place through the pasta machine. Starting on the thickest setting, roll it, fold it; roll it again, etc…, until it gets as thin as possible. Right now you are activating the gluten.
After you have repeated this step about 7 times on a setting one you will send it through each other setting once time through until you have rolled it out at the thinnest.
Halfway through the stretching process you will probably want to cut it in half since your sheet of pasta will be extremely long. You are looking to have nice clean silky sheets. Cut each sheet in half.
Place the ricotta mix in a pastry bag and squeeze a little bit of the mix about an inch apart on a pasta sheet. Take a pastry brush and brush your other beaten egg lightly around the ricotta mix. Fold the other half of the sheet over and press all the air out. This is very important as you will want to make sure there is no possibility the ravioli can explode in the water. Cut your ravioli and set on a floured surface.
Start a pot of salted water to boil, and make your brown butter sauce:
