I love fetuccini -- however you spell it.....

I always either end up with hard noodles or nasty soggy ones. I never let the water stop boiling, which I've read is a good secret to cooking it correctly. And I check the noodles all every 30 seconds or so just to try and not get to the soggy point. But... I always end up with 1 or the other. Any suggestions??

try cooking in boiling salted water until slightly underdone

I have never had a problem with this. i always taste a noodle. When it is still firm to the bite I take it out of the water & drain.

Fetuccine is great, I eat it regularly, but I've never made it myself.

I always eat a noodle to test my pasta. I take it off the stove before it becomes all the way done because it will finish cooking after you drain the water of the pasta.
