Prepare five 12g red bean paste balls, dust with flour and set aside (My photo is of lotus seed paste)
Prepare 120g egg whites (from 4 large eggs) in a mixing bowl and add 1 tbsp sugar. I tried using store-bought egg whites in a carton but they failed to keep solid after beating to stiff peaks so I do not recommend using those.
Use electric mixer on high speed to mix for 2 minutes or until egg whites are stiff. You know when they’re done when you can stick a chopstick in it and it doesn’t move
Sift 1 tbsp corn starch and 1 tbsp flour together into the egg whites in 2 intervals. Use the electric mixer for approx. 5 seconds per interval to mix together
Heat oil to between 140˚C to 150˚C or 280˚F to 300˚F. Try to keep the oil at this temperature so that the egg white balls stay as lightly golden as possible
Place approx. 15g of the egg white mixture in an ice-cream scoop, a ladle or a small bowl. Give it a few taps to get rid of any air pockets Try to pack it in as much as possible without deflating the egg whites to prevent oil from getting in and creating pockets of oil
Place a red bean paste ball into the centre of the egg white, push it in a bit but not enough to expose it on the outside
Add another 10g of the egg white mixture to cover the red bean paste entirely
Smooth out the egg whites and form a ball
Once the oil reaches 140˚C or 280˚F, gently drop the egg white ball into the oil
Use a ladle to gently drizzle some oil over the top of the egg white ball so that they will not stick to one another
Once the egg white ball stiffens a bit, turn it over. Continue turning each ball to get even colouring. Fry for approx. 6-8 minutes, depending on the size of the balls. The balls should be cooked by 4 minutes but cooking it longer will help it keep its shape. If you’re not fussy about having a round shape then frying for 4 minutes will be enough
Remove from oil and lay them on some kitchen towels to absorb excess oil
Increase the heat of the oil until you reach 175˚C or 350˚F. Put the balls back into the oil for 1 minute. This step will help make the balls less greasy and make the outside crispier
Sprinkle with icing sugar or granulated sugar It’s also common to use coloured granulated sugar. Just put some white granulated sugar in a plastic bag, add a few drops of food colouring and shake it until the colour is even
Serve while hot
