10 per tray but bigger (possibly twice as big) compared to the previous $18 mango tray I got from the same place a week ago. probably not as sweet and slightly sour but I'm still happy with them. pick carefully as there are some bruised ones. plenty of boxes when I left.
I think these are better than the $12 sour and mostly tasteless strawberries that I picked up last week and went to the bin.
Normally a sour taste means the slightly underripe. Leave for a few more days and they will sweeten abit. Calypso (in my experience) this season have been fairly underripe in store.
