These dates are edible at every stage of ripening. So, feel free to order some and slowly enjoy these exotic fruits.
These fresh dates begin to ripen and turn yellow (as in photograph below and will be delivered to you as), dates are crunchy, like an apple, with a faint honey flavor. For those who do not enjoy the astringency that comes with young fresh dates, further ripening can then take place on or off the tree. At the next stage, dates turn brown and chewy and acquire the intense sweetness they are famous for. Finally, they darken even more and become dried dates.
