We returned from Vienna on April 18th and brought back a Sacher-Torte and and an Imperial which was the second of two Plat gifts given from two stays at the Bristol ( well, I liked the first one so much I selected that as the gift on the second stay

)
We ate the Sacher a week ago and it arrived was in good condition they do recommend that they both be kept in the refrigerator until consumed ( date stamped before May 20 th) and I brought them in my carry on.
It been about 3 weeks between the two but it seems they were both very similar makeup/ingredients and must be so since there was some kind of legal fight by Sacher against other bakers who they claimed had copied the torte.
I would think shipment from Europe especially in the summer would be a iffy proposiion.
