Semolina. It just tasted like really fresh pasta. Light delicious pasta. To be honest, I prefer the one my mom used to make, with eggs. But I can totally live with the egg free version.
I ordered it off of Amazon.
You really need '00' or strong flour plus semolina to make pasta dough. I don't like egg pasta and prefer dry pasta to fresh pasta. I did make it once using eggs and there is definately a distinct taste.
I think that I'm going to experiment and make some very soon. Prehps I should add some tofu to the dough to subsitute the eggs ?
Your tagiatelle look really good!
