This rustic-looking pie is the ultimate in summer simplicity. It requires just one crust, with the edges folded over the fruit filling, made from homemade dough that bakes up crisp and flaky. While it chills in the fridge, use this time to pit the sour cherries, which are then flavoured with a bit of almond extract. The balance between the cherries’ tartness and sweetness makes for an irresistible dessert you’ll want to make again and again, all summer long.
