When ready, use roughly a quarter of the dough at a time and cover the rest that you aren't working with with a damp cloth or the plastic wrap/cling film to save it drying out. Prepare a large baking sheet/tray by dusting with flour.
As you work with each piece, flatten it out slightly, dust with flour then put it through your pasta roller on the widest settings a few times (about 2-3 times should be fine) until smooth. Dust with flour in between rolling if at all sticky. Then move up the settings rolling once or twice at each settings until you get to the thickness you would like - I usually go to around 6 on my pasta maker. It should be very thin, with you able to see through it slightly, but not breaking up.
If using a ravioli mould, lay the sheet of pasta over a ravioli mould then press down the frame to make indents. Fill each with a teaspoon of filling.
Lightly dampen around the edges of each ravioli with a little water then place another pasta layer to place on top, or fold over the rest of the piece you have if it is long enough, trying to avoid any air getting inside the cavity. Press down with a rolling pin to seal then trim the excess pasta from around the side of the mould and add to a piece to use later. Carefully remove each ravioli from the mould and lay them on the floured trays.
If not using a mould, you can make them by laying the first piece of pasta out, dotting teaspoons of filling out evenly in lines with gaps between, dampening between then laying another layer on top. Then gently press in the areas between the filling to seal and cut.
Repeat with the rest of the pasta and filling. Once all the pasta has been used and you are ready to cook, place a few ravioli at a time in a shallow pan of boiling water for around 2-3 minutes until they rise up to the top, then remove with a slotted spoon and cook the rest in batches.
I often served these with a simple browned butter - warm the butter in a small skillet over a medium-low heat until you can see it brown slightly and the smell is becoming nutty. Drizzle over the top of the cooked ravioli. Alternatively, a cream sauce would also be good.
