Prawns cook fast and absorb flavour fast. NEVER marinate prawns longer than 30 minutes in acidic marinades — the acid will start "cooking" them and they'll turn rubbery.
The best cuts of prawns for this marinade are: king prawns (shell-on or peeled), tiger prawns.
King prawns and tiger prawns are ideal — they're large enough to handle on the BBQ and have a sweet, firm flesh that stands up to bold flavours.
Get precise cooking times for any meat, cut, and method. Never over-cook or under-cook your BBQ again.
