Preheat oven to 350F and spray or grease and lightly flour a 9″x5″x3″ loaf pan
Sift flour, baking powder and soda into a large mixing bowl, add salt and whisk. Set aside.
In a medium bowl, mash the ackee (a whisk or a rubber spatula does this well, alternately, you could pass the ackee through a sieve or blend it). Add the sugars then the eggs followed by the oil mixing till well combined.
Make a well in the centre of the flour mixture and pour in the ackee mix.
Gently mix till it is well combined. Pour into prepared loaf pan and smooth top with a spatula.
Bake for 30 minutes, then reduce temperature to 325F and bake for another 10 to 15 minutes till done. – A skewer is inserted in the loaf will come out clean and/or it will spring back when lightly touched.
Remove from oven and allow to cool in the pan for 15 minutes. Turn out of pan and let it cool completely on a wire rack.
Slice and enjoy!
