A traditional cake from tropical countries… as soursop is really hard to find anywhere else! This particular version has layers of sponge cake soaked in rum syrup, filled with pastry cream and soursop puree. Covered and decorated with torched Italian meringue and more soursop puree! I lovely remainder of my childhood favorites. By the way, I found a can of soursop in syrup at an Asian store and it was a TREASURE!
