Cut vegetables: Thinly slice an onion, cut a carrot into thin strips, chop a scallion, and put them in a bowl.
Add batter ingredients: Add water to the bowl and combine lightly, then add flour and potato starch and combine well.
Prepare a pan: Put oil (2 cm/1 inch) in a frying pan and heat to 160 °C (320°F).
Deep-fry: Scoop the vegetables with a spoon and slowly put them in the pan. When one side is golden brown (about 1-2 minutes), flip it over and deep-fry until golden brown.
Notes
Substitute: You can substitute potato starch with corn starch.
Storage: Please enjoy this kakiage immediately, or you will lose the crispy texture over time. I don't recommend keeping them in the fridge.
Portions: 4 thin Kakiage
It is important to cut the vegetables into even slices so that they cook evenly and the kakiage will have a uniform texture.
Use cold water rather than lukewarm water. The batter will be light and airy and crisp up beautifully when fried.
Scooping the vegetables with a large spoon and making them round can help ensure that each kakiage is roughly the same size, which will help them cook evenly.
Keep the temperature of the oil between 160 °C - 170 °C (320°F - 338°F ) for best results.
While deep-frying, make a couple of small holes inside to make it easier to fry.
Place the cooked kakiage on a wire rack or paper towel to remove the excess oil, which will help keep them crispy.
