Hi Eli
Well I have tried once buying 3 or 4 Bursa from a local supermarket and that was enough !
They were very expensive, at least twice the cost of our local black Smyrna, not given enough time to ripe, were too soft at touch, and the taste was to forget!
Still I am convinced that under normal circumstances it's a very good fruit.
Hope to have one rooted this season to try, may be in 3 or 4 years from now.
