Little parcels of goodness @Barking Mat love Chinese ones, Kings on Odiham Hampshire we used to stop there just to have them not been lately but used to be superb
Almost bought an Eastern European one in Canada. It was like a plate with flip up hinged bits, so you rolled the pastry over it then peeled it away and it left a load of pastry rings. Dump the filling in the middle then flip them over. Not as slick as this one but did a dozen at a time, because Canadian Ukrainians do like their perogies!
