Jerk marinade (sauce) is hot, spicy, aromatic and mildly sweet.
If the scotch bonnet is too hot for you, remove the seeds and white membrane inside (You might need to use gloves) or use a less spicy pepper like the jalapeno.
Grind the allspice seeds before adding the other ingredients for a smoother blend.
The addition of fruits will decrease the intensity of the jerk flavour but add extra sweetness to the marinade.
In the absence of allspice, combine 1 teaspoon ground cinnamon + 1 teaspoon ground cloves (Kanumfari) + pinch of ground nutmeg.
If you don't have brown sugar use white.
Use either white vinegar or apple cider vinegar.
