Maine wild blueberry pie is one of the canonical American regional pies: as inseparable from the food identity of Downeast Maine as chowder or lobster rolls, and equally dependent on an ingredient that can only come from one place. Wild lowbush blueberries (Vaccinium angustifolium) from the barrens of Washington County have a flavour intensity, depth, and aromatic complexity that no cultivated blueberry can replicate: they are small, densely pigmented from skin to flesh (unlike highbush cultivars, which have pale interiors), and suffused with the wild, slightly resinous quality of a fruit that has never been domesticated in the conventional sense. The Maine blueberry pie is a two-crust affair: a flaky butter pastry that provides maximum contrast to the deeply flavoured filling. The filling is minimally adorned (sugar, a little lemon, a touch of flour or cornstarch) because the berries need no embellishment. The pie should be intensely blue-black in its filling, deeply flavoured, and not overly sweet: the tartness of the wild berry is the point. Maine blueberry pie reached national awareness through the mid-20th century proliferation of roadside diners and home-cooking cookbooks across New England, and remains one of the few American regional foods that genuinely cannot be replicated with a commercially available substitute.
Ingredients
Pastry
300 g plain flour, plus extra for dusting
1 tsp caster sugar
0.5 tsp fine sea salt
200 g cold unsalted butter, cut into 1 cm cubes
6 tbsp ice-cold water, or as needed
Filling
800 g wild blueberries (Vaccinium angustifolium, preferably Downeast Maine), or dark wild-type blueberries, fresh or frozen
120 g caster sugar
3 tbsp plain flour or cornflour
1 tbsp lemon juice, freshly squeezed
0.5 tsp finely grated lemon zest
1 pinch fine sea salt
Finishing
1 medium egg, beaten with 1 tbsp milk, for egg wash
1 tbsp demerara sugar, for sprinkling
Method
Make the pastry: pulse the flour, sugar, and salt together. Add the cold butter and work it in quickly (either by rubbing with your fingertips or by pulsing in a food processor) until the mixture has pea-sized lumps of butter throughout. Add ice-cold water one tablespoon at a time, mixing until the dough just comes together but is still rough. Divide into two discs, wrap, and refrigerate for at least 1 hour.
Preheat the oven to 200°C (fan 180°C) with a baking sheet on the middle rack. Mix the blueberries with the sugar, flour, lemon juice, lemon zest, and salt in a large bowl. Set aside.
Roll one pastry disc on a floured surface to a circle about 33 cm in diameter and about 3 mm thick. Transfer to a 23 cm deep-dish pie tin. Press gently into the base and sides, leaving the excess hanging over the edge.
Pour the blueberry filling into the pastry-lined tin, mounding it slightly in the centre — it will settle as it bakes.
Roll the second pastry disc to the same size. Lay it over the filling. Trim the overhanging pastry to about 1.5 cm, fold the edge under, and crimp firmly with a fork or by pinching with your fingers. Cut four or five steam vents in the top crust. Brush with egg wash and scatter over the demerara sugar.
Bake on the preheated sheet at 200°C for 25 minutes, then reduce to 175°C and bake for a further 30 to 35 minutes until the crust is deeply golden and blueberry juices are bubbling visibly through the vents. If the edges begin to darken too fast, cover them loosely with foil.
