I tasted about 3 sugar loaf –E4 mangoes. It does not taste like coconut cream mango to me. It’s more like pineapples. One of them with white flush tasted to me is a mix of sweet and sour pineapple. One of them with light yellow flush tasted to me like sour pineapple. And the third one was perfect it was like a sweet pineapple. They had more pineapple flavor than the pineapple pleasure mango. There was a significant variation in the taste from mango to mango. It’s because they may not be picked or ripens at the perfect stage. Its flush has some white color and pineapple flavor, but not sweet as the sugar loaf pineapple. Its taste may not be good as a perfect coconut cream mango but is unique. I like to grow this mango tree because it’s unique flavor. I never tasted the m4 mango.
Yes, proper harvest time is a problem with mangoes that basucally stay green. When properly picked, the E4 will have a pale yellow flesh and can even have a hint of texture that some may deem as minimal fiber (as does Pickering).
While I agree it is not the Hawaiin Tropic coconut flavor found in the Coco Cream but is definitely coconut. I do find it odd that you detected no coconut with your E4s. I can only think harvesting issues were the cause. In the same respect, what flavors did you detect in the Pineapple Pleasure? Harvest with this fruit also olays a role but in any event, the flavors in ever one I have ever gad have been pineapple, just ranging from tart to super sweet with an acidic balance.
