Blueberry Pie in a Cast-Iron Pan
or egg yolk, for glazing the pastry
Make the pastry dough and chill it.
Preheat the oven to 350℉ (180℃).
Meanwhile, place the blueberries in a pan over medium heat with the lemon juice and sugar.
Cook until soft, tasting for sweetness.
If there is too much juice, pour some off and save it to make a fruit sauce later.
Roll out the pastry dough into a circle an inch larger than a 9- inch cast-iron or enameled cast-iron skillet.
Place the circle on top of the pan and press down the edges with the blade of a butter knife.
Brush with milk or egg yolk and bake for 20 to 30 minutes, or until the pastry is golden brown.
