...for the whole eggs and allowing parmaggiano.

For the method, yeah, I used to pre-mix eggs, cheese, and pepper in a separate bowl too; still probably do it about half the time. (Went with the mixing-on-top-of-the-spaghetti version above perhaps mostly not to be seen as hypocritical for criticising that blog-comment guy's unneccesary use of an extra saucepan, then use an extra bowl myself. Though, come to think about it, his crime is still much the greater, for cooking stuff in cornstarch, never mind the washing-up.) But putting the heat back on? Naah... Look at the pan just before and as he's serving up: That's clearly scrambled egg up around the rim.
