Step-by-Step Instructions

1. 1.Prepare Water for Steaming

   Place a pot with water on the stove and turn on the heat to prepare for steaming.

2. 2.Peel Sweet Potatoes

   Remove the outer skin from 500g of sweet potatoes using a peeler.

3. 3.Cut Sweet Potatoes

   Cut the peeled sweet potatoes into small, manageable pieces for steaming.

4. 4.Rinse Sweet Potatoes

   Rinse the cut sweet potatoes thoroughly in a bowl of water.

5. 5.Steam Sweet Potatoes

   Place the sweet potato pieces in a steamer basket over the boiling water. Steam for 15 minutes or until they are soft enough to be easily mashed with a fork.

6. 6.Mash Sweet Potatoes

   Transfer the steamed sweet potatoes to a large bowl. Add 1/4 teaspoon of salt and mash them until completely smooth.

7. 7.Add Flour and Butter

   Sift 1 cup of all-purpose flour into the mashed sweet potatoes. Add 1 tablespoon of butter to the mixture.

8. 8.Knead Dough

   Using a gloved hand, knead the mixture until it forms a soft, cohesive dough that is not too sticky.

9. 9.Shape Doughnuts

   Take a portion of the dough (approximately 1/8 cup using a measuring cup for consistency). Flatten it into a disc and create a hole in the center to form a doughnut shape. Repeat for all dough.

10. 10.Prepare for Frying

    Lightly grease a banana leaf placed on a plate with cooking oil. This will prevent the shaped doughnuts from sticking.

11. 11.Heat Oil for Frying

    Heat a sufficient amount of cooking oil in a deep pan or wok over medium heat. Ensure the oil is at the correct temperature before frying.

12. 12.Fry Doughnuts

    Carefully place the shaped doughnuts into the hot oil. Fry them until they turn a beautiful golden brown color on both sides, turning occasionally with a wooden spoon.

13. 13.Remove and Drain

    Once the doughnuts are golden brown, remove them from the oil using a slotted spoon and place them on a paper towel-lined plate to drain any excess oil.

14. 14.Fry Remaining Doughnuts

    Continue frying the rest of the shaped doughnuts in batches until all are cooked to a golden brown.

15. 15.Prepare Sugar Glaze

    In a clean wok or pan, combine 1/3 cup of sugar, 1 cup of water, and 1 tablespoon of cooking oil. Bring the mixture to a boil over medium heat. Continue boiling until the water reduces by half and thick, bubbly syrup forms.

16. 16.Coat Doughnuts with Sugar

    Turn off the heat. Immediately add the fried doughnuts to the hot sugar syrup. Toss them continuously with a spatula until the sugar crystallizes and evenly coats each doughnut.

17. 17.Serve Kuih Keria

    The Kuih Keria are now ready to be served. Arrange them on a plate, optionally lined with banana leaves.

18. 18.Optional: Powdered Sugar Coating

    For an alternative coating, continue tossing the doughnuts in the pan until the crystallized sugar breaks down into a fine powdered sugar coating.

19. 19.Enjoy Kuih Keria

    Enjoy the delicious Kuih Keria, either with a crystallized or powdered sugar coating. Note that the sugar coating may melt slightly in room temperature over several hours (e.g., 6 hours at 28°C).
