Blueberry Pie in a Cast-Iron Pan - pastry

Method

• Make the pastry dough and chill it.
• Preheat the oven to 350F (180C).
• 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.
