Lac-Saint-Jean Blueberry Pie

A deep-blue Quebec-inspired pie filled with wild-style blueberries, maple sugar, and a hint of lemon beneath a crisp, buttery pastry lid. The filling is thickened just enough to slice cleanly while keeping the berries juicy.

How to prepare

1
Whisk 270 g of the flour with the salt in a large bowl. Cut in the cold butter with your fingertips until the mixture ranges from coarse crumbs to pea-sized pieces. Sprinkle in the ice water, mixing just until the dough holds when pressed; do not knead.
2
Divide the dough into two pieces, making one slightly larger for the bottom crust. Flatten each into a disk, wrap, and chill for 30 minutes, until firm but rollable.
3
Combine the blueberries, 120 g of the maple sugar, tapioca starch, lemon zest, and 2 tablespoons lemon juice in a bowl. Toss gently until the berries are evenly coated and let stand for 10 minutes while the oven heats to 200°C.
4
Roll the larger dough disk into a 30 cm round on a lightly floured surface and fit it into a 23 cm pie plate, leaving a 2 cm overhang. Pour in the blueberry mixture and dot the surface with any loose butter crumbs from the bowl, if present.
5
Roll the second dough disk into a 27 cm round, cut 5 or 6 vents in the center, and lay it over the filling. Trim the edges, fold the overhang under itself, and crimp to seal. Brush the top with beaten egg and sprinkle with the remaining 30 g maple sugar.

6
Bake at 200°C for 20 minutes, then reduce the oven to 190°C and bake for 30 to 35 minutes more, until the crust is deeply golden and the filling bubbles visibly through the vents. Cool on a rack for at least 3 hours so the juices set before slicing.

Why this recipe works

Wild-style blueberries provide concentrated color and aroma, while maple sugar deepens their flavor without masking their acidity. A modest amount of tapioca starch absorbs excess juice and leaves the filling tender rather than gummy.

Storage and reheating

How to store it

Cool the pie completely, then cover and refrigerate for up to 4 days. It can also be frozen, well wrapped, for up to 2 months.

How to reheat it

Reheat individual slices in a 160°C oven for 10 to 15 minutes, or serve cold. Do not microwave the whole pie, as the crust will soften.
