Use ice water for the batter. This is really important to prevent the batter from absorbing too much oil.
Tip 2: Batter (Tempura Batter Recipe)
Do not make the batter ahead of time.
Try not to over mix the batter and not to coat ingredients with the batter too much.
Tip 3: Frying Order
If you are frying both seafood and vegetables, fry vegetables first. Then, fry seafood. Fry vegetables at 340F degree and fry seafood at 350F degree.
Tip 4: Oil Temperature
To check the temperature of frying oil, drop a little batter into the oil. If the batter comes up right away instead of sinking to the bottom of the pan, it's about 360 F degree. If the batter goes halfway to the bottom and comes up, it's about 340F degree. This is said to be the right temperature to fry tempura.
