cook stirring occasionally for 8-12 minutes, start checking for doneness at the five minute mark by tasting a noodle if it's uncooked you'll know it because it will taste like raw flour and feel weird in your mouth, a cooked noodle will taste delicious, and be soft remember noodles rolled out very thin, and cut thinly may be done in as little as 5 minutes or even sooner so start checking as early as you need to so you avoid over cooking your noodles
