Tempura is a wet batter associated with Japanese cuisine and is used to add a crisp, light coating to seafood and vegetables. Tempura batter absorbs less oil than some of its heavier counterparts, making it a healthier option for deep-frying and giving the dish a less greasy finish.
Make sure that the ingredients you are coating are thoroughly dry to ensure that the tempura batter stays crisp.
When making tempura vegetables, partially cook the vegetables before coating in batter as they won’t have time to cook through before the batter becomes crisp and golden.
