Dates are one of my most favourite things.
I reckon your dates might be mazafati variety from Bam in Iran. If so, that's my very favourite type of date. Within the caramel/honey/toffee/chocolatey range of date flavours, they're at the "chocolate" end of the scale. I pick them up cheap from my local greengrocers once a year just after Ramadan. They keep, so I bought 5 boxes (don't know when I'll get to see them again...)
I've not tried this, but apparently the "thing to do" is to soak them overnight in goat's milk before pigging out on them.
