Since these days high-quality cooking oils are used for deep-frying, it is not always necessary to remove excess oil. However, remove excess oil if there is an odor, and when you want the tofu to thoroughly soak up flavor. For quickly simmered dishes, place the deep-fried tofu into a strainer and pour boiled water all over it. For inari sushi (sometimes called inarizushi, stuffed fried tofu pouches) and simmered dishes with deep flavor, place the deep-fried tofu into boiling water and allow to boil for about 5 minutes before using.
