Hotate Tempura is a crispy and delicious way to enjoy scallops. To make this tempura, you will need fresh hotate (scallops), tempura batter mix, ice-cold water, vegetable oil for frying, and dipping sauce. Start by preparing the tempura batter according to the instructions on the package. Make sure to keep the batter cold by adding ice cubes to the water. Heat the vegetable oil in a deep pan or fryer to 350°F (175°C). Dip the scallops into the tempura batter, making sure they are fully coated. Carefully place the battered scallops into the hot oil and fry until golden brown and crispy, about 2-3 minutes. Remove the scallops from the oil and let them drain on a paper towel. Serve the Hotate Tempura with a side of dipping sauce, such as soy sauce or ponzu sauce. The tempura batter adds a light and crispy texture to the scallops, making them irresistible.
