Hello Nancy,
We have some lovely saskatoon berries up here this year. (I'm not sure what they're called in the U.S.). Blueberries may be substituted in these recipes.

Saskatoon Tarts

1 cup sugar
1 cup sour cream
3 Tablespoons flour
1 Tablespoon lemon juice

Heat ingredients until sugar dissolves. (Careful that it doesn't burn). Add 2 cups berries. Pour into pie shell or tart shells and bake at 350 deg. F. Bake tarts for 30 minutes.


Saskatoon Squares

1 cup butter
1 tsp. baking powder
3/4 cup sugar
Pinch of salt
2 eggs
2 cups flour

Filling:
2 cups saskatoons
1/4 cup sugar
1 cup water
1 tsp. vanilla
1 tsp. lemon juice
1 tsp. cinnamon
1 Tbsp. cornstarch, dissolved in 1/4 cup water

Mix first 6 ingredients as for pie crust. (I used a food processor). Take 1/2 the mixture and line bottom of 9 x 12 inch pan.

Filling: Boil together and thicken with cornstarch dissolved in water. Spread over top mixture and cover with remaining pie crust mixture. Bake at 350 deg. F. until light brown, approx. 20 minutes.
