Deep frying without schnitzels sticking to each other
Sometimes it's better to say: Don't put them in the deep fryer: add some pepper, paprika and butter on top of them and put them in the oven at 175°C (350°F) for 20 minutes.

If you insist on using a deep fryer: 


Ensure you have a fryer large enough so they don't touch one another


OR


Deep fry them one by one in a small fryer and then microwave them all together for 1 minute at 750W just before serving them.
