Best steely day of my life was with some tiger prawns I found at the bogi launch I cured overnight with some amermans steel cure sprinkled over them.

I cut them into bait size pieces put them in ziploc and sprinkle cure on top fill bag with air and shake. A little cure goes a long way with the prawns. I'll add egg juice, anise, or other smelly for fun but the cure alone is fine.
