A year in Canada in Ontario: Dining Posted June 27, 2008 Try to find some northern Ontario wild blueberries. They're so different from the farmed blueberries you get in the grocery store. If you travel north you could pick them yourself or buy them by the side of the road later in the summer. It depends on the weather when they become available.They're generally smaller than the cultivated ones and combine an incredible sweetness with the tang of the forests they grow in.For a great blueberry pie, combine 4 cups blueberries, a squeeze of lemon juice, a cup of sugar, 4 tablespoons flour, a dash of salt (1/8 teaspoon) or so. Toss (not too gently, break up some of the berries a bit), pour into your favourite double crust. Bake at 450 for ten minutes and then 350 for 30 to 40 minutes. Cover the crust if it looks too brown.
