Ashta Mystery Fruit

Hi, Bianca here. I know that I promised beet cake, and it is forthcoming, but I have far more urgent matters to discuss. I am visiting my lovely partner's family in Lebanon where I have encountered a new mystery fruit. Ashta fruit is new to me, and to Lebanon where they have named it for the Arabic word for a local and especially decadent sweet cream. I'm pretty sure I have seen this fruit before, but I cannot recall it's name in English. Do you have any ideas? It is, by the way, entirely reminiscent of its namesake. You peel the lumpy bits off the outside and suck up the delicate and creamy innards.
