Chikuwa Isobe-age is a simplified variation of tempura made with Japanese fish cakes coated in a crispy batter flavored with powdered nori (aonori). This recipe is quick, easy and can be used for many different ingredients!
Start heating a pot of oil to 180 °C (356 °F). While you wait, cut 4 chikuwa in half lengthways, then cut in half again diagonally crosswise.
Take a large bowl and add the 2 tbsp cake flour, 2 tbsp potato starch and 1 tbsp dried green laver powder (aonori). Crush 1 tsp bonito flakes in your hand to make a fine powder and sprinkle it into the bowl. Mix until all the ingredients are evenly distributed.
Pour 60 ml sparkling water into the dry ingredients and gently stir until combined.
Add the chikuwa to the bowl and mix until evenly coated.
Once the oil is hot, add the battered chikuwa and fry for 1 minute on each side.
Transfer to a wire rack and rest for a few minutes to drain any excess oil.
