Substituting quinoa flour for wheat flour in egg pasta
I have never tried making pasta with just quinoa flour, but use a mix of potato starch and corn flour. So my pasta contains a lot of starch.

The issue is that the pasta gets really short and need to be handled quite carefully after rolling it. I have used it to make tagliatelle, ravioli, spaghetti, lasagna and tortellini with great success (my comparison is store bought pasta, not normal pasta as I haven't eaten that in 10 years when I found out I was allergic).

I don't really have a recipe, as I never follow them. But for one person I add two egg yolks, one whole egg, ~1 tablespoon of olive oil and some random mix of the flour until it feels smooth and nice to work with. I have found the resting time of this pasta to be essential, and I always allow it to rest for at least 20 minutes.
