Amber's Blackberry-banana pie

The August that Amber and Jasmine were 3 years old, the blackberries were thick near our home on Bowen Island. One day, out of the blue, Amber said: "Let's make a blackberry-banana pie!" Now tell me, who could resist an invitation like that! Now we make them every year.

• Double crust pie or tart shells
• 3 - 4 cups blackberries
• 3 bananas, sliced
• ½ cup sugar
• 3 Tbsp cornstarch
• egg white

Place banana slices on bottom of pie shell(s). Mix together the sugar and cornstarch, and sprinkle abut 1/3 of the mix, lightly over bananas. Heap blackberries on top of the bananas. Sprinkle with the remaining sugar mix. Brush edges with egg white. Place top crust on, sealing the edges. Slash air holes in the top. Bake at 425 for about 40 minutes.
