The main difference between Jamaican and regular curry powder is that the Jamaican version is usually less spicy. In traditional Jamaican dishes, heat is generally added in the form of fresh chilies, hence the blend itself do not contain much heat.   Jamaican curry powder usually contains allspice, which is not found in the regular ones.   Both kinds of curry powder will work in this recipe, but do adjust the amount of spice used according to your preference.
