5-7 tbsp (80-105) ml cold water / cold carbonated water
4 tsp (20ml) vinegar
6 tbsp (48g) cake flour
3 tbsp (30g) potato starch
1 tbsp (6g) aonori
1/4 tsp salt
1/8 tsp black pepper
Remove broccoli stem from florets. Cut the broccoli into bite size pieces. Wash and drain well. Add the broccoli to a container with 2 tbsp of the cake flour. Cover the bowl and shake to coat the broccoli in the flour.
In another bowl, mix together the cake flour, potato starch, aonori, water, salt and pepper. If the batter is quite thick, add 1 extra tbsp of water. The batter should be slightly looser then tempura or pancake batter.
Add oil to a pan and heat to 160-170 C(320-338 F). Dip the broccoli into the batter and then carefully place into the oil. Fry for 1-2 minutes and then turn each piece and fry other side until golden brown. Remove broccoli and place on a wire rack to let excess oil drip off.
