Heat the oil in a high pot or in a deep fryer to approx. 180 °C. Pull the onion skewers in portions through the beer batter and fry in the hot oil for 3-5 minutes until golden brown. Drain on kitchen paper. Serve with the dip
If you like, you can vary the onion skewers with olives or peperonis, for example. Put them on together with the onions and deep-fry
