Heat oil in a kadai - First add one string onion to check oil temperature. If there is no immediately bubbles coming then you need to wait for few seconds.
After few seconds add another string again you can see immediate bubbles coming and it starts to slowly come up. This is the right oil temperature.
Keep flame in medium. Now add a small batch of onion strings.
After few seconds flip over.
Let it fry in medium flame.
