1. Preheat smoker to about 250F and set up for indirect cooking. I smoked mine on the incredible Nomad Grill, which makes it easy to cook this recipe anywhere.
2. Mix blueberries, sugar, corn starch, lemon zest, orange zest and lemon juice together,
3. Divide your pastry into equal portions and drop a dollop of the blueberry mixture into each, then mould the dumplings into individual balls.
4. Place your dumplings into a foil tray, then sprinkle liberally with sugar and place a knob of butter on the top of each.
5. Pour enough milk in your tray to sit at about 1/4 inch high.
6. Smoke until pastry is golden brown and crispy. Use a mild fruit wood for smoke, being careful not to over smoke the dumplings.
7. Once ready, remove dumplings from smoker and let them rest for about 15 minutes. Serve with vanilla ice cream and enjoy!
