Clean and scale the fish under a little cold water, don't use too much water as you'll lose some of the flavour. Make a few slashed on the outside of the fish.
Combine the thyme, smoked paprika, onion powder, haitian hottie chilli sauce and the lager.
Wearing some plastic / latex gloves rub the mixture all over the prepared fish and then place some lemon pieces into the bellies, wrap in cling film and place into the fridge to marinade for at least an hour.
Serve with what ever you like, be it french fries or a crispy salad. Enjoy with another Jamaican red stripe lager.
