Harum Manis or Arumanis mangoes have a vibrant green skin with large, light-yellow dots. The fruit maintains its green coloring even when ripe and is ready to eat right off the tree. Harum Manis mangoes have an overall elongated and elliptical shape; they are slightly larger than palm-size and can weigh up to one pound. The skin is thick, and tough, protecting the soft flesh within. The lemon yellow flesh has a strong, sweet aroma and flavor with a slightly bitter aftertaste. The flesh is thick and juicy and mostly fiberless. Harum Manis mangoes have a medium-sized stone. Harum Manis mangoes, like other mango varieties, are high in vitamins A and C and many essential nutrients and minerals. They contain potassium, iron, calcium and magnesium. Harum Manis mangoes are also high in soluble fiber. Drinking the juice of an Harum Manis mango is said to have a refreshing and hydrating effect on the body.
