Take out a pot or wok. Fill with a layer of vegetable oil. Then place on medium-high heat. When the oil is hot enough (reference video), grab a piece of the battered squid and dip it into the wet batter. Then carefully place it into the oil. Fry up only a handful at a time - don't try to cook everything at once. Fry until light golden brown. Then strain-out the leftover tempura flakes. And repeat!
