Portokalopita....
I'd seen this described as sort of a Greek bread-and-butter pudding. It's crushed, dried-out filo pastry mixed with a custard and, once baked, drenched in an obscene amount of orange syrup. It was surprisingly light, and the orange flavour really popped. I'll definitely make this again. Served with some tangy Greek yoghurt to balance the sweetness it was a real winner...
