Instant noodle is mainly made of wheat. However, if using wheat only, the noodles gets lack of chewy feature. In this regard, noodle has been made of potato starch and wheat recently. The potato starch has a feature of being cooked faster than wheat and the feature is used for making bowl instant noodle. In a nutshell, bowl instant noodle is made of wheat together with potato starch unlike other ordinary types of instant noodle (Shin ramyun, neoguri, etc) because the potato starch makes the noodle to be cooked fast and the bowl itself is sized smaller to transmit heat faster.
