Step 1

With a stand mixer: Add flour, baking powder, baking soda (if using), salt, the egg water mixture and oil into the bowl. Mix and knead on low speed for about 8 minutes. Rub a little oil on your hands (to prevent sticking) and remove the dough.

Step 2

Manually: use a silicon spatular to mix and combine all the ingredients into a rough-looking dough. Cover and rest for 15 mins. Coat your hands with oil (to prevent sticking). Use your fist to press the dough. Then use fingers to fold the dough from the side towards the centre. Repeat the movement until the dough becomes smooth (at this stage it should be soft but not sticky).

Step 3

Divide the dough into two equal portions. Shape each one into a smooth ball. Coat with oil then cover with cling film.

Step 4

Rest the dough for 2-4 hours at room temperature. Or, keep it in the fridge overnight. The next morning, wait for at least 1 hour until it comes back to room temperature.

Step 5

Before handling the dough, start heating up the oil for deep frying.

Step 6

Transfer the dough pieces onto the work surface (or a chopping board) dusted with flour. Use your hands to flatten each piece into a rectangle shape (about 10×25 cm/4×10 inch). Remember not to knead it again but handle it gently.

Step 7

Lightly dust the dough with flour to prevent sticking. Then cut each piece into 10 equal strips.

Step 8

Lay one strip on top of another. Press the centre with a chopstick lengthways to stick them together. Repeat the procedure with the rest of the dough pieces (dust with flour where necessary).

Step 9

Once the oil reaches 190°C/374°F (see note 4), turn the heat down to low. Gently stretch the dough then carefully lower it into the oil (be careful not to splash).

Step 10

When it comes up to the surface, roll it around continuously with a pair of chopsticks. Once the dough stops expanding and is evenly golden, transfer it to a plate lined with kitchen paper (to soak up excess oil).

Step 11

Repeat the procedure to cook the rest of the dough. You may cook two sticks at the same time, but do not fry more at once since this will decrease the oil temperature too much.

Step 12

Doughnut sticks taste best when warm. You may store leftovers in an airtight bag in the fridge for up to three days or in the freezer for 2 months.

Step 13

Reheat the chilled ones in a frying pan (without oil) over low heat until warm. Flip several times to heat evenly.

Step 14

For frozen ones, you may heat it up in the oven (preheated at 180°C/ 356°F) for 5 mins without defrosting. Or defrost first then warm up in a frying pan.
