Instant noodles are pre-cooked and dried noodles with seasoning powder and/or seasoning oil for sale. Seasoning is usually put in a separate package, although in the case of cup noodles, seasoning is usually dispersed in the cup.
Some instant noodle products are sealed and can be reheated or taken out of the packaging/container for eating. Dry noodles are designed to be cooked or soaked in boiling water before eating, but they can also be eaten dry.
