Mix all ingredients thoroughly in a bowl and set aside in the fridge until your dough is rolled out.

Remove the pasta dough from the refrigerator and let it sit at room temperature for a few minutes. Next, unwrap and knead on a lightly floured surface for a few minutes by hand. Cut the dough into manageable pieces about the size of the palm of your hand.Press each piece on a flat surface with your hands to flatten it to about 1⁄4 inch (6 mm) thick (cover the pieces you aren't rolling yet in plastic wrap).

Run each piece through a pasta roller starting with the widest setting. Fold the sheet in half and run through on the widest setting a total of three times. If it gets too wide you can fold the sides in to make it thinner. If it rips or tears, simply fold it over and start again.

Run it through the next lowest setting two more times, folding in between.Then run the sheet through once at the next lowest setting and continue until your desired thickness is achieved. We typically roll it to the 5th lowest setting for ravioli. Every roller is different, so you may need to try out a few thicknesses to find what you prefer. Lay your pasta sheet on a flat surface dusted with flour to fill and cut your ravioli. To prevent the dough from drying out too much, we prefer to roll out one sheet at a time and make the ravioli from each sheet before rolling out another sheet.

Alternatively, you can roll the pasta dough out with a rolling pin, but be prepared to really put some muscle into it. You want to roll the sheet out until you can see the light through it when you hold it up.

Next add 1 tablespoon of the filling about 3 inches apart on half of the sheet. Fold the sheet in half onto your filling scoops, bringing the two short edges together. Carefully press the sheets together around each scoop of filling. Press out as much air as possible. Finally, use a ravioli cutter or a knife to cut your sheet into 3 x 3 inch squares (7.5x7.5 cm), then set the ravioli aside on a parchment-lined and lightly flour-dusted baking sheet.

Start the sauce by putting the cream, ripped sage leaves and peppercorns in a medium saucepan. Bring to a simmer (very gentle boil) and hold until the cream has reduced by half, stirring with a rubber spatula to make sure it doesn't stick to the pan every couple of minutes. This will take about 15-20 minutes or so - be patient.

Once reduced, strain the solids and return to the saucepan. Add the parmesan, chopped sage, vinegar and salt. Stir and simmer for 2 minutes. Taste and add more salt if necessary.

For the toasted breadcrumbs: Add 2 Tbs butter to a skillet on medium-low heat. When butter is done bubbling, add breadcrumbs. Stir often (you can turn the heat up a little) and when the breadcrumbs have golden brown remove from heat. They will turn to toasty brown very quickly so be careful here. Remove to a plate to cool.

For the crispy prosciutto: Use the same skillet you used for the breadcrumbs (if you want) heat on medium heat and add 3 thin slices of Prosciutto. They will crisp up quite quickly so you only want them on for 5 seconds or so per side. Remove to cutting board and chop into small bits - you can use slices or dices or whatever.

For the crispy sage leaves: In a small saucepan with about ½ inch of oil, heat on medium-high for a few minutes. Pick out some sage leaves you want to crisp (large nice looking ones). Use a tester sage leaf in the oil - it should sizzle right away but not discolor. It will be in the oil for about 5-8 seconds. Remove to paper towels to drain the oil. The sage leaves should be a darker green (not brown) and not limp and greasy. If you take them out and they are greasy limp, put them back in the oil for 2-4 seconds (they should bubble and crisp as soon as they hit the oil as the water in the leaves hasn't completely been removed).

Once sauce and toppings are done, you can cook your ravioli. Bring a large pot with water to a slight boil. Once it boils, add salt (2 tablespoon per 6-8 quarts of water). For fresh ravioli, add the ravioli to the gently boiling water until it floats (approximately 2-3 minutes). For store-bought, follow the cooking instructions on the packaging and start cooking while you prepare the toppings.

When the ravioli are done, remove them from the water with a slotted spoon from the water to serving plates and add sauce and toppings.
