Preheat the cooking oil between 150 °C (302 °F) and 160 °C (320 °F). Sift 70 g Okinawan brown sugar into a large mixing bowl using a sieve, use a spatula to help work the lumps through. Use a knife to cut up any especially large pieces.
Crack 1 medium egg(s) into the bowl and add ½ tbsp neutral flavoured oil. Whisk thoroughly until smooth and well incorporated.
In a separate bowl, mix 125 g cake flour, 1 tsp baking powder and 1 pinch salt together until well distributed.
Sift the dry ingredients into the wet ingredients and mix them together using a spatula until a dough is formed. It should have the consistency of soft cookie dough.
Tip: Use two spoons to divide the dough into equal pieces (I make twelve) and lay them on a silicone baking mat or greaseproof paper.
Once the oil is heated, roll each piece into a ball and carefully place it in the oil. I recommend greasing your hands for this as the dough is very sticky.
Deep fry until golden and cracked. This will take about 4-5 minutes. (When they are ready, they should float and roll around in the oil.)
Transfer to a wire rack to drain any excess oil.
Serve and enjoy!
