TK, you could do it! If I can do it, anyone can. I have no special abilities, just have been cooking for a very long time. Not because I find the cooking inherently enjoyable, but I love to eat something delicious, especially when I know exactly what is in it. Like Bea said, you can add a lot of stuff to pasta (in or on), to increase the nutritional value.
If you have a rolling pin, you don't need the machine. All the machine does is flatten the pasta to a very thin layer. And it cuts the dough into fettucine or linguini.
For ravioli, once you get the thin strip of dough, the machine part is done. Then it is cut into the desired shapes. A regular pizza cutter would work. A scraper or large knife could also work, pressing it straight down, not trying to drag it across/through the dough. The ravioli just wouldn't have the zig-zag edge.
IDK how others make a mushroom filling but here is what I did. I figured excess moisture in the filling could cause the ravioli to explode so I simmered minced mushrooms & onions in a little butter over very low heat until they had shrunk a LOT, about 30 mins. Then cooled and mixed with a beaten egg and a couple different kinds of shredded white cheese until it is a thick paste.
If they are making the tortellini manually, I'm not surprised they're expensive because of the time involved. Tortellini and ravioli are basically the same thing, just a different shape.
Bob, I can't wait to make some cannoli. I'm confused by the myriad of wildly different recipes for both the shells and the filling. Do you have your gramma's recipe? If so, and it's not a secret, I would love to see it!
