Put water in a pot and bring to a boil. Add in salt, lemongrass, peppercorns, ginger, chicken cube and chicken feet.
Simmer the chicken feet for 30 to 45 minutes or until tender. Turn off heat and remove from the liquid and put in a bowl. Set aside.
Make the batter by combining the batter ingredients: flour, vinegar, cooking oil, baking powder, pepper, salt and water.
Mix until it becomes smooth and the lumps disappear. Put 4 to 5 pieces of chicken feet in the batter and dip until well coated.
Heat oil in a wok or frying pan about 3 cups. Then put the battered chicken feet and fry until crispy and golden brown. Do the same procedure on the rest of the chicken feet.
Then put the fried chicken feet in a paper towel lined plate. Serve with sweet chili sauce or spiced vinegar dipping sauce.
