This was my first pie and it came out really well. I didn't find blueberries so I went for frozen strawberries instead. The filling ended up being a bit mushy and runny, probably because it was frozen and had extra water. I'd suggest using fresh berries if possible. I didn't have yuzu juice so I squeezed some orange juice instead and it was a great decision - oranges have some sweetness to it. The dough was perfect - buttery and not too dry.
