Combine the Szechuan, salt and pepper with the flour and dry the prawns.
Dip the prawns in the flour and coat evenly.
Dip the prawns in the egg mixture.
Return the prawns to the flour mixture and arrange on a non stick dish brushed with oil.
Cook at 190 C for about 10 minutes until crisp and golden.
Notes
Top tips
If you want more of a fine pepper mix I use a small coffee grinder just for spices like this. It also works well for cardamom pods and black pepper too.
The dipping of the prawns can get quite messy so I like to use one hand for flouring and the other for egg dipping. This will stop you from getting crusty hands
