Ingredients
- 150g all-purpose flour
- 1/2 tsp salt
- 2 tsp vegetable oil
- 100ml boiling water
- 1 leek, sliced
- 2 small sweet potatoes, peeled and chopped into small cubes
- 1 tbsp soy sauce
- 1/2 tbsp sesame oil
- 1/2 tbsp sugar
- 30ml water
- 1 tbsp soy sauce (for steaming liquid)
- 1 tsp sugar (for steaming liquid)
- Vegetable oil, for garnish and frying
- Sesame seeds, for garnish
Instructions
- Step 1: Place the peeled and cubed sweet potatoes in a pot of water. Bring to a boil over high heat and cook for about 8 minutes or until tender. Drain and set aside.
- Step 2: In a bowl, combine the flour, salt, and vegetable oil. Gradually pour in the boiling water while stirring with chopsticks until the mixture forms shaggy dough. Transfer the dough onto a clean surface and knead for 3 minutes. Cover with cling film and set aside.
- Step 3: Heat a frying pan with a splash of vegetable oil over medium heat. Add the sliced leek and sauté briefly, then add the cooked sweet potatoes, 1 tbsp soy sauce, sesame oil, and sugar. Stir well to combine into a chunky paste. Remove from heat and set aside.
- Step 4: Knead the dough again for 1 minute. Divide it into 8 equal pieces.
- Step 5: Roll each piece into a thin circular wrapper about 3 inches in diameter.
- Step 6: Place a spoonful of the filling in the center of each wrapper. Fold the edges up and pinch them together in a circular motion to seal the dumpling completely. Gently flatten each dumpling to form a thick disc. Repeat for all wrappers.
- Step 7: Optional: Pour vegetable oil onto one plate and sesame seeds onto another. Lightly dip the smooth side of each dumpling first into the oil, then into the sesame seeds to coat.
- Step 8: Heat a frying pan over medium heat and drizzle with oil. Place the dumplings sesame seed side down and fry for about 3 minutes until slightly golden. Flip them over, then pour in 30ml water, 1 tbsp soy sauce, and 1 tsp sugar. Cover with a lid and steam for 8 minutes. Monitor closely and add more water if it evaporates too quickly to prevent burning.
- Step 9: Remove the cooked oyaki from the pan. Serve warm and enjoy!
Tips & Variations
