Published in both Jamaican books, this sauce recipe is spicy with a hint of sweet and a nice acid/salt balance--everything you want in a hot sauce. Mango can replace pawpaw (papaya) too. And, habanero can replace scotch bonnet but beware that the scotchies bring not only heat but an awesome floral undertone not always found in habanero. Eat on eggs, fried pork chop, tortilla with melted cheese. It'll take them all to another level. Here's the full recipe from Lucinda's Authentic Jamaican Kitchen, Wiley, 2006 (filled with many great, flavorful easy recipes including the best jerk pork and chicken, or said by many a real Jamaican born cook).
