OK, I've noticed that some of my friends refer to all pastas as noodles. As in "we had noodles with tomato sauce" instead of "pasta with tomato sauce". Now I know that pasta in Italian essentially means "dough" and you'll find the term in many bread recipes and other recipes that call for dough to be made.. But I always and I mean always refer to Italian "noodle products" as pasta. And I refer to Asian "pasta products" as noodles, i.e. soba noodles not soba pasta; spaghetti carbonara not noodles with creamy bacon sauce.
Is the term "noodles" for all flour/water/perhaps egg mixtures a North Americanism? Is there a difference between "noodles" and "pasta"?
