Use a knife to cut the skins off the onions and then cut into rings. Discard ends which are too small or odd shaped for rings.
Pour half of the flour into a bowl
Pour the remaining flour into a 2nd bowl
Add garlic powder and salt
Pour beer into flour mix and use a whisk to combine Note 5
Dip your rings one by one into flour
Next dip rings into beer batter, then shake off excess (hold rings above batter bowl to do this)
Turn wok on to medium, allow to heat
Drop a little batter into the wok to see if the temperature is ready for cooking. It will sizzle straight away if it is.
Add onion rings one by one to the wok and work in batches (6-8)
Cook for 4-5 mins per batch, allow the colour of the rings to guide you. They will go from plate to to yellow and when golden are cooked.
Serve with salt and sweet chilli dipping sauce
