Working with one triangle wrapper at a time, place onto a clean surface. Using a flat bladed knife (such as a butter knife), spread a tablespoon of the pork mince filling over one half of the wrapper. (Doesn't have to be perfect, just roughly spread out thinly - see images above in post). Place one prawn towards the bottom then fold the bottom wrapper over the prawn, roll up once then tuck the pointed side in and keep rolling tightly until there is about 5cm of wrapper left. Place one whole coriander leaf onto the wrapper and spread some glue over the end 2-3cm of the wrapper. Finally, continue to roll up to seal completely. Set aside and repeat with remaining wrappers, prawns and coriander leaves. Cover and chill until ready to fry.
