I'll teach you a few ways to identify rusty noodles/
The first, the simplest way, is that after the noodles into the pot, do not stir, wait for the noodles to float up the premise is the water below the boiling with chopsticks gently flip, remember here is not stirring, but flipping, the noodles up and down to fall a position, so that the noodles evenly heated, so that the noodles will not appear to cook through the situation. This way, the noodles will not be undercooked. Flip a few times later, use chopsticks to pick out a noodle, with a finger pinch off, see whether the noodles have white spots, if there are white spots, that is not cooked, continue to cook, to the point of cool water, waiting for the water to open, and then in the pick out a noodle, with a finger pinch off, to see whether there is a white spot, if there is no longer basically is cooked , you can fish out.
The second method, water boiling into the noodles, floating up to turn the noodles, and so on, after the water boiled, point to the pot of cold water, point after the cold water to see if all the noodles are floating, if all the noodles are floating state, then the noodles are not ripe, if the noodles are half-floating state, then it is basically ripe, if the noodles are completely sinking state, all encroachment of the water, the noodles are already cooked!
The third method, this method is more suitable for home production of hand-rolled noodles, knife cut noodles, etc., because their own home made noodles, basically wide, and after, so the cooking time will be very long, this time many people do not grasp, for example, this kind of noodles, the same operation into the noodles, and so on the first time the water boiled, add cool water to the appropriate, flip the noodles, in the waiting for the water to boil, and then add the appropriate cool water to the water boiled, in the waiting for the water to boil, and then add the appropriate cool water to the water boiled, the water boiled, the water boiled. cool water, waiting for the water to open, add cool water in the appropriate, this third time after the water opened, waiting for the boiling water completely over the noodles, this time to fish out the noodles basically cooked, so that the cooking of the noodles out of the pot will be just right.
