Omani Dates.

From my Oman files.

Fossil records show the date palm has existed for at least 50 million years.
Dates have been found on a number of neolithic sites, which would suggest that they were being eaten as much as 7,000 to 8,000 years ago.
They provide a range of essential nutrients, and are a good source of dietary potassium. The sugar content of ripe dates is about 80%; the rest consists of protein, fibre, and trace elements that include boron, cobalt, copper, fluorine, magnesium, manganese, selenium, and zinc.
Oman has more than 250 varieties of dates, and each region of the country will tell you theirs are the best. But I think of all, it has to be the ‘Khalas’, found in the Sharqiya and Dhahirah region, also Al Rostaq. The fruit is bright yellow, oval-shaped, and usually eaten fresh or half-dry.
Dates and qahwah arabiyya (coffee) is a fundamental part of Omani hospitality; even the poorest family will offer coffee & dates when one visits.
