Taken from epicurious .com and posted for ZWT. "Our appreciation of peri-peri prawns comes from Mozambique, where these shellfish are cooked in the traditional Portuguese style." Cook/prep time DOES NOT include time for sauce to 'age'. According to the recipe, 2 weeks is the optimal time for this flavorful sauce to age. You will not use all of the sauce made, for this recipe; there will be leftover sauce, for next time!
