Mix together 200 g all-purpose flour, 10 g double-acting baking powder and ½ teaspoon salt.
Add in 120 ml water and ½ tablespoon oil, knead the dough for 4-5 minutes until it is smooth and shiny, then cover and set aside to rest for 2 hours.
Lightly dust your work surface with flour, place the dough on the flat surface, and sprinkle some flour over. Roll out into thin flat dough about 3-4 mm thickness.
Cut the flat dough into strips, about 2.5cm (1 inch) wide and 15cm (6 inches) long.
Dip a wooden/bamboo skewer in water, dab the wet skewer in the center of the dough strip. Place another strip of dough on top, and then gently press down into the center of the dough with the skewer. This allows both dough strips to stick together and remain fused during frying.
Deep-fry at 180°C (390°F), flip constantly to ensure breadstick puffed up evenly.
