Saskatoons (also known in the USA as juneberries or serviceberries) are quite popular in our area of Manitoba. There is a large grove of them growing around the lake just 10 minutes from town, so naturally we went foraging this summer. We picked berries during swimming lessons every day for roughly two weeks, with two larger picks on Saturdays. In total we have foraged (free) wild saskatoons to get about 18 Litres of them (that's about 4 1/2 ice cream pails). Needless to say, I've already made several saskatoon pies, and will be making several more to freeze.
Saskatoon Pie Filling:
4-5 cups saskatoons
3 Tbsp cornstarch
1/2 c sugar
Toss all together until the berries are coated. Pour into unbaked pie crust. Top with another crust and poke holes. Bake at 425 for 15 minutes then lower to 350 for another 50 minutes.
