In a deep frying pan, heat vegetable oil over medium heat until it reaches approximately 375°F (190°C).
Carefully spoon dollops of the onion and batter mixture into the hot oil.
Fry 4-5 fritters at a time, ensuring the pan isn’t crowded.
Cook each side for 2-3 minutes, or until they attain a golden-brown hue.
Use a slotted spoon to transfer cooked fritters to a plate lined with paper towels, letting excess oil drain.
