Stoned Sayer Dates

Sayer dates are a type of date(google it)
Stoned would mean the Date still contains its pit ( stone) , as opposed to being a pitted date.

Stoned means pitted. It's more of a British usage.

As always Punkey is full of ignorance. Pitted is rarely used over here, 'stoned' is the norm.

And you're right, it means to have taken the stone out, not kept it in.

Thank you all.
