Manara's Polish-American co-founder catching up late here to say I never tried that ice cream, but I do recommend eating knafeh in the West Bank and fattet hummus in Gaza! The food in in West Bank vs Gaza is quite different... I think Gaza is particularly good... but unfortunately it's almost impossible to get there unless you're a humanitarian worker or a journalist.

NOTE: if you work in tech and want to mentor in Palestine, check out Gaza Sky Geeks and Code for Palestine. They organize on-site travel for select volunteers (full transparency: I'm involved with both organizations)
