To make the tempura batter, combine 1/2 cup of all-purpose flour, 1/2 cup of cornstarch, 1 cup of chilled seltzer, 1 egg and a pinch of salt. Stir the batter to combine.

Keep the batter in the fridge while batches are frying in the oil.
Before making the tempura, heat at least 1 inch of canola oil to 360 degrees Fahrenheit in a large cast iron skillet. The oil shouldn't be smoking, but it should be sizzling. Saveur magazine suggests adding in 1/8 cup of sesame oil to the pan before frying the seafood and vegetables to add depth to the flavor profile. Allow the oil to return to 360 F before adding the frying ingredients.
While the ingredients are frying, sprinkle a bit of batter over them. This technique makes the fried tempura crunchier. Remove the leftover batter bits from the oil with a slotted spoon.Learn more about Cooking
