Peel and slice the apple into desired thickness or dice it into small cubes. Place in a pot.

Add lemon juice or vinegar to the pot with the apples. Adjust the amount based on your preference for sourness.

Add a pinch of salt, cinnamon powder, and 2 tbsp sugar to the pot. Simmer on low heat until the apple becomes soft and mushy.

Let the cooked apple mixture cool down. Place it on dumpling wrappers and fold them like dumplings.

Press the sealed edges with a fork to secure them firmly.
