- 225g cold unsalted butter, cubed
- 1 tsp sea salt
- 7 tbsp ice water

- 900g fresh blueberries
- 100g cane sugar
- 30g cornstarch
- 1 large lemon, zested and juiced
- 0.5 tsp ground cinnamon
- 0.25 tsp ground ginger
Instructions:
- Cube your 225g unsalted butter into small pieces and put them in the freezer for 10 minutes.
- Whisk 320g flour and 1 tsp sea salt in a large bowl.
- Use a pastry cutter to work the cold butter into the flour until it looks like coarse crumbs with some pea sized chunks.
- Stir in 1 tbsp apple cider vinegar and 7 tbsp ice water, one tablespoon at a time, until the dough just holds together when squeezed.
- Divide into two discs, wrap in plastic, and refrigerate for at least 1 hour.
- In a separate bowl, toss 900g blueberries with 100g cane sugar, lemon zest, lemon juice, 0.5 tsp cinnamon, and 0.25 tsp ginger.
- Roll out one disc on a floured surface and fit it into your pie dish.
- Pour in the berry mixture and top with the second rolled disc or a lattice pattern.
- Crimp the edges tightly and cut vents in the top.
- Bake at 400°F (200°C) for 20 minutes, then drop to 375°F (190°C) for another 35 minutes until the crust is golden and the filling bubbles thickly.
